Welcome to the Quicklane Tire & Auto Center @ Al Packer White Marsh blog. Today, let’s talk about the effect of tire tread depth on braking. When talking about stopping power, most of us Middle River drivers tend to focus on our brakes. But our tires are where the rubber meets the road. So having good brakes isn’t enough. Safe Middle River drivers need to have tires with enough traction to translate braking power into stopping power.
Let’s focus on stopping in wet Middle River conditions. In order for a tire to have good contact with the road, it has to move the water out of the way. If it can’t move the water, the tire will actually ride on top of a thin film of water.
That’s called hydroplaning. If it’s really bad, Middle River drivers can actually spin out of control. At best, you won’t stop as fast.
So how does a tire move water? It has channels for water to flow through. Look at your Ford tire and you’ll see channels: channels that run around the tire and channels that flow across the tire. They’re designed to direct water away from the tire so it can contact the road better.
And the deeper the channel, the more water it can move. A brand new Quicklane Tire & Auto Center @ Al Packer White Marsh tire has very deep channels and can easily move a lot of water. As the tire wears down, the channels become shallower and can move less water. When it wears down enough, it can seriously affect your ability to stop your Ford on wet Middle River roads.
So that’s why it’s so important to replace our Ford tires when they get worn. Consumer Reports and other advocate groups call for a standard of 3/32 of an inch and they have the studies to prove it.
By comparison, you’ve probably seen the wear indicator that’s molded into tires. When tires are worn 3/32 of an inch, the tread wear bar is visible. So the recommended standard has twice the tread depth as a completely worn out Ford tire.
At Quicklane Tire & Auto Center @ Al Packer White Marsh, we want our customers to know that the deeper recommended tread depth makes a big difference. Stopping distances are cut dramatically on wet Middle River roads. A safe stop from MD freeway speeds with 4/32 of an inch of tread would result in a crash with worn out tires.
There’s an easy way to tell when a tire’s worn to 4/32 of an inch. Just insert a quarter into the tread. Put it in upside down. If the tread doesn’t cover George Washington’s hairline, it’s time to replace your Ford tires. With a Canadian quarter, the tread should cover the numbers in the year stamp.
Many Middle River car owners have heard of this technique using a penny and Abe Lincoln’s head. That measure gives you 2/32 of an inch – half the suggested amount. Of course, Ford tires are a big ticket item. Most of us in Middle River want to get as many miles out of them as we can. But there’s a real safety trade-off. It’s your choice.
So you love our job, and your family life is great: You have achieved balance. But can you the same for your wheels? You can tell if your tires are out of balance by vibrations at higher speeds. If one of the front tires is out, you feel the vibration in the steering wheel. If it’s a back tire, you’ll feel the vibration in your seat.
Tires and wheels are pretty heavy. When a tire is mounted on a wheel, it is usually not perfectly balanced. So the tire technician will spin the tire on a machine to determine where it’s too heavy. He will then place weights on the wheels in strategic locations to balance it out. When a tire is out of balance, it actually bounces down the road instead of rolling smoothly. Since the average size tire rotates at about 850 revolutions per minute at 60 MPH, it is actually slamming into the pavement 14 times a second. That’s where you get your vibration.
Most people are surprised at how smoothly their car rides after balancing all four wheels.
Most high-quality tires hold their balance pretty well. They just get out of balance gradually with normal wear and tear. If you suddenly feel a vibration, it is probably because you lost a wheel balancing weight along the way. Definitely get a balance if you feel a vibration, change your rims or have a flat repaired. Putting off a needed balance job leads to excessive tire wear, wear to your shocks, struts, steering and suspension parts. wheel balancing not only improves your ride and handling, but also can save you some big repair bills and possibly an accident. Additionally, you will get better gas mileage.
Some people have their tires balanced at every rotation. Others do it every other time. Check your owners’ manual for your requirements, or ask your technician. Doing thus will put you on the path to mechanical wheel balance
A lot of our viewers have asked whether or not they should use their severe service maintenance schedule, which is listed in their car owners’ manual. It can be confusing. Let’s clear the air on this subject. Cricket Killingsworth is from QMI/Heartland, a manufacturer of automotive products and fluids. She’s been in the automotive business for 20 years and is a speaker, a trainer, and a writer. Cricket says there’s so much confusion on this topic because, “Most owners’ manuals actually have two maintenance schedules. Sometimes these are called ‘regular service’ and ‘severe service’. Sometimes they’re simply called Schedule 1 and Schedule 2. A severe service schedule recommends that things like an oil change, air filter replacement, and transmission service be done more often: either in fewer miles or in less time.
Manufacturers create these specific schedules for each vehicle they make. So there isn’t one generic schedule that applies to all cars. In addition to your owners’ manual, White Marsh automotive repair centers subscribe to information services that provide the maintenance schedules for every vehicle – so they can help you know when to take care of needed services. Below is a typical definition for severe service.
Most trips are less than four miles
Most trips are less than ten miles and outside temperatures are below freezing
You drive in very hot weather
The engine is at low speed most of the time (not on the highway)
Stop and go driving
You operate your vehicle in dusty or muddy conditions
You tow a trailer, regularly carry heavy loads or carry a car-top carrier
It’s common sense: Just a few minutes at freeway speeds allows the moisture in the oil to evaporate. Very short trips, or trips of less than ten miles when it’s very cold, don’t allow the engine to heat up enough to get rid of the water. And water in the oil leads to damaging sludge. Also, towing and heavy loads raise operating temperatures and cause fluids to breakdown more quickly. Dusty and muddy driving means that more dirt will get past the air filter to contaminate the fuel system and engine oil.
The bottom line is that you need to decide for yourself if the regular or severe service schedule is right for you, based on your driving. Look at your owners’ manual, or talk with your Quicklane Tire & Auto Center @ Al Packer White Marsh service advisor who can help you know which schedule to follow. Quicklane Tire & Auto Center @ Al Packer White Marsh is located at 9801 Pulaski Highway, White Marsh MD.,
Here is what a fleet manager said recently: “Since city miles are generally tougher on vehicles than highway miles, we use the manufacturer’s severe service schedule as the basis for our preventative maintenance program. We massage those schedules over time, increasing or decreasing the service intervals so that they make the most sense. There is a little bit of art to go along with the science.
Make an honest evaluation of your driving habits. Unless you do mostly MD highway driving in moderate weather, you’ll likely have a fairly good amount of severe service mixed in. Some people just want to play it safe and follow the severe service recommendations, rather than analyzing how they drive each month.
You know, at Quicklane Tire & Auto Center @ Al Packer White Marsh we get a lot of people asking about how to prepare their car for a trip. That’s a big deal. You could be driving through mountains and deserts in some pretty lonely areas outside of White Marsh so you may be anxious to know that the car is up to the task and won’t leave you stranded.
You really do need to plan ahead for a major road trip – there are a lot of things to get ready. Where should you start? You could start with the tires. Look them over for tread wear and check to see that they are properly inflated. Take a quick test drive around White Marsh to see if you can feel any vibrations: are the wheels are in balance? Is the car tracking straight? Is the alignment ok?
The next thing is a full service oil change to make sure all of your fluids are topped off and you have fresh oil for the trip. And if your car has over 75,000 miles, you may consider putting in the high-mileage formulation to clean harmful sludge deposits in the engine. You may also need a new PCV valve and an engine air filter.
How about your transmission and brakes? Have you had your transmission and brakes inspected in the last six months?
How are your wiper blades? There’s nothing like not being able to get rid of the bug juice on a long road trip away from White Marsh.
Consider also having the coolant system serviced – you want to stay within the manufacturer’s recommendations. If you’re towing a trailer you’ll want to be keep in mind that you’ll be going a long way under severe conditions.
A lot of folks overlook severe conditions like towing, or summer heat, or driving on dirt roads. Plan ahead for your next road trip – we want you to get there and back.
Brakes really aren’t optional equipment. And taking care of them isn’t optional either.
A regular brake inspection is on every car’s maintenance schedule. An inspection will check your brake system and let you know if there are any problems. Of course, if you’re having trouble with your brakes, get your car into a White Marsh or Dundalk service center right away. And watch out for these problems:
Low or spongy brake pedal
Hard brake pedal
A brake warning light that stays on
Constantly squealing or grinding brakes
Vibrations or clunking sounds when you apply your brakes
There are two types of brakes: disc and drum. Disc brakes have a rotor that’s attached to the axle. Calipers straddle the rotor, kind of like the brakes on a bicycle. Drum brakes are more common on back wheels. Pads, called shoes, push against the inside of the drum to slow the vehicle.
There are several things that need to be serviced on the brake system. First, the brake pads and shoes wear out with use, and become too thin to really help. If the brake pads wear away completely you can damage the rotors. The calipers can grind grooves in the rotor. Then the rotor must either be resurfaced or replaced and that can be expensive. But putting it off is dangerous because your vehicle won’t stop as quickly. Sometimes rotors warp or crack and must be replaced.
Brake fluid is also important. When the brakes are applied, the pressure in the fluid activates the brake pads or shoes. Not enough fluid, not enough pressure to brake properly. Also, water builds up in the brake fluid over time, which leads to corrosion, leaks and brake damage, and with hard use, the brakes could severely fade or even fail. You should change the brake fluid when your manufacturer recommends it.
There are different grades of brake pads. There are regular, metallic and ceramic – higher grades cost more, but give better braking performance and smoother operation. It’s OK to upgrade your brake pads. But, never use a grade that’s lower than what the manufacturer recommends.
Be sure to properly maintain your brakes because it’s a lot cheaper than paying your nearest Baltimore area body shop after an accident.
So, when are your tires actually worn out? This is a question a lot of us in White Marsh MD ask ourselves. For many, the answer is ‘when they no longer pass a safety inspection’. But waiting that long can have a serious impact on your safety.
The U.S. Federal government doesn’t have any laws for tread depth, but 42 of the states, and all of Canada, do have regulations. They consider two-thirty-seconds of an inch to be the minimum legal tread depth. Two other states, including California, consider one-thirty-second to be the minimum and six states have no standards at all. Call us at Quicklane Tire & Auto Center @ Al Packer White Marsh (just call (443) 777-5050) to find out what your requirements are in the White Marsh MD area.
Since 1968, U.S. law has required that a raised bar be molded across all tires. When tires are worn enough that this bar becomes visible, there’s just 2/32” of tread left. But does that older standard give you enough safety?
Well, Consumer Reports issued a call to consider replacing tires when tread reaches 4/32”. And the recommendation is backed by some very compelling studies. Now before we go into the studies, you need to know that the big issue is braking on wet surfaces.
We tend to think of the brakes doing all the stopping, but you also need to have effective tires to actually stop the car. When it’s wet or snowy in White Marsh MD, the tread of the tire is critical to stopping power.
Picture this: you’re driving over a water-covered stretch of road. Your tires actually need to be in contact with the road in order to stop. That means the tire has to channel the water away so the tire is actually contacting the road and not floating on a thin film of water – a condition known as hydroplaning. When there’s not enough tread depth on a tire, it can’t move the water out of the way and you start to hydroplane.
This is where the studies come in. We think you’ll be surprised. A section of a test track was flooded with a thin layer of water. If you laid a dime flat on the track, the water would be deep enough to surround the coin, but not enough to cover it.
A car and a full-sized pick-up truck were brought up to 70 mph and then made a hard stop in the wet test area. Stopping distance and time were measured for three different tire depths. First, they tested new tires. Then tires worn to legal limits. And finally, tires with 4/32” of tread were tested – this is the depth suggested by Consumer Reports
When the car with the legally worn tires had braked for the distance required to stop the car with new tires, it was still going 55 mph. The stopping distance was nearly doubled. That means if you barely have room to stop with new tires, then you would hit the car in front of you at 55 mph with the worn tires.
Now with the partially worn tires – at the depth recommended by Consumer Reports – the car was still going at 45 mph at the point where new tires brought the car to a halt. That’s a big improvement – you can see why Consumer Reports and others are calling for a new standard.
Now without going into all the details, let us tell you that stopping the truck with worn tires needed almost 1/10 of a mile of clear road ahead to come to a safe stop. Obviously this is really a big safety issue.
The tests were conducted with the same vehicles, but with different sets of tires. The brakes were the same, so the only variable, was the tires.
So, how do you know when your tires are at 4/32”? Well, it’s pretty easy. Just insert a quarter into the tread. Put it in upside down. If the tread doesn’t cover George Washington’s hairline, it’s time to replace your tires. With a Canadian quarter, the tread should cover the numbers in the year stamp.
Now you may remember doing that with pennies. But a penny gives you 2/32” of an inch to Abraham Lincoln’s head. The quarter is the new standard – 4/32”.
Tires are a big ticket item and most people in White Marsh MD want to get the most wear out of them that they can. But do you want that much more risk just to run your tires until they are legally worn out? For us, and we would guess for many, the answer is “no”.
Well, Mr. Washington, let’s go out and look at my tires.
New cars cost so much these days. Add financing and insurance and, well a new vehicle may not seem so attractive. A lot of White Marsh, MD people are hoping to make their cars last a lot longer.
The good news is that with the current state of automotive engineering and manufacture, there’s no reason a modern vehicle can’t be made to last for a 150,000 miles or more.
There is an old saying that says, ‘a stitch in time saves nine’ and that is really true when it comes to taking care of your car. A great example is coolant service.
Over time, coolant becomes corrosive and actually starts to damage your radiator and other parts. That’s why you need to have your cooling system serviced on a regular schedule.
The same is true for your power steering system, brake fluid, air conditioning system, differential and transmission. And your oil changes should be done right on schedule to avoid the build up of harmful oil sludge.
Don’t let your brake pads go too long before they are worn to the point that they cause damage to rotors. Preventive maintenance is a great way to keep your operating costs down.
Now this is a lot to remember. Quicklane Tire & Auto Center @ Al Packer White Marsh can keep on top of this stuff. We can tell you what your manufacturer recommends and help you with a plan to take care of it.
Bottom line – take care of this stuff on schedule and you will reduce operating costs, prevent costly damage and maintain your warranty coverage. Call Quicklane Tire & Auto Center @ Al Packer White Marsh today for an appointment; you can reach us at (443) 777-5050.
Take good care of your car, and it’ll take good care of you.

Today we want to talk about a very important system in our cars – the cooling system. It’s one of those things that you don’t give much thought to until it fails and then you’re stranded by the side of the road.
Cooling systems fail more often than any other mechanical system – usually because of neglect. Don’t you hate it when something breaks, and you could have done something to prevent it?
The good news is that if you take care of your cooling system it can keep working for the life of your car.
Here at AutoNetTV, we emphasize preventive maintenance services like replacing your coolant according to the factory schedule. But the various parts that make up the cooling system need attention too. The major components of the cooling system are the water pump, freeze plugs, the thermostat, the radiator, cooling fans, the heater core, the pressure cap, the overflow tank and the hoses.
It sounds complicated, but we don’t have to be experts – we can leave that to our Friendly service technicians at Quicklane Tire & Auto Center @ Al Packer White Marsh. But, having an overview will help us remember to take care of our cooling systems.
Most people would be surprised to know that burning fuel in your engine produces up to 4,500 degrees of heat. And all that heat has to be dealt with. If the heat can’t be drawn off the engine, the pistons will literally weld themselves to the inside of the cylinders – then you just have to throw the engine away and get a new one. That would cost thousands of dollars.
Now the water pump is what forces the coolant through passages in the engine to absorb heat. The pump is driven by a belt that needs replacement from time to time. And the water pump will eventually wear out and need to be replaced. Spending some money on replacing the belts and water pump is much less than the cost of repairing the massive damage that can be done when an engine seizes.
There’s another little part of the coolant system that protects the engine. It’s called a freeze plug. If you remember from high school chemistry, water expands when it freezes. In very cold areas, the coolant can actually freeze when the vehicle is left sitting.
It is hard to believe, but the expanding frozen coolant can actually crack the engine block. The freeze plugs fit into the engine block. They fit tight enough to withstand the pressure of a running engine, but can expand or pop out if the coolant freezes. These little things save a lot of engine blocks.
That brings up a good point. An engine has to work in all kinds of temperatures – extremely hot as well as very cold. How does the cooling system adapt to external temperatures as well as varying operating conditions?
Well, it’s much like the way you keep your house at a comfortable temperature all year round – with a thermostat. The thermostat in your car controls how much coolant flows through your engine. When the engine is cold, it restricts coolant flow until the engine comes up to an efficient operating temperature. Then it starts opening up to move more coolant to keep the temperature within a specified range.
The thermostat needs to be replaced from time to time as well. It’s easy to diagnose a failed thermostat and is fairly inexpensive to replace. We can do this for you at Quicklane Tire & Auto Center @ Al Packer White Marsh in White Marsh, just give us a call: (443) 777-5050. Now we’ve been talking about all this heat we’ve got to get rid of, but haven’t really talked about where it goes. That’s where the radiator comes in. The hot coolant passes through the radiator. Air flows past the cooling fins and cools the coolant.
The radiator has two tanks that hold coolant: sometimes one the top and bottom or one on either side. If you have an automatic transmission, one of the tanks will also contain a second tank that cools the transmission fluid. Large SUV’s and trucks often have a separate transmission cooler. So when you drive around White Marsh, the air is forced past the radiator. But driving doesn’t produce enough air flow. So the radiator has cooling fans that force fresh air over the radiator. These fans may be powered by a belt or by electric motors.
Now, you also have something called a heater core. The heater core is like a mini radiator. A small fan blows air over the heater core and into the passenger compartment of your vehicle. That’s how you warm your car when it’s cold out.
Next is the radiator cap. With most newer cars around White Marsh, you never remove the radiator cap, except to replace it. You add coolant through the overflow tank. The radiator cap is also called a pressure cap, because its job is to maintain pressure in the cooling system.
High pressure raises the boiling point of the coolant, so it cools more effectively even in very demanding conditions. That is why you need to replace the cap from time to time. They recommend changing it out every time you replace your coolant.
Coming back to the overflow tank, it is needed because when the coolant gets hot it expands and the overflow holds the extra volume. The tank helps maintain the proper level of coolant and keeps air out of the system. You should never open the radiator cap or over flow tank when the engine is hot. This could lead to serious burns.
What else do we need to do to keep our cooling systems working well? Well, there are the hoses that hook all of these pieces together. They’re obviously very tough to deal with the pressure and high temperatures. But they do get worn. Sometimes they get spongy from the heat. Sometimes they lose their connection to the radiator, water pump, etc. It’s a great idea to have your White Marsh service center inspect your hoses at least once a year and replace them, if needed, before they break.
Quicklane Tire & Auto Center @ Al Packer White Marsh can help you check your cooling system and make any necessary adjustments or repairs. Give us a call at (443) 777-5050.
If you aren’t currently using synthetic motor oil in your White Marsh vehicle, maybe now’s the time to consider it. Need more information? Well, synthetic motor oil is a substitute for petroleum based oil.
Synthetic oil doesn’t gel or gum-up like petroleum based oil and it doesn’t vaporize as easily. It protects better in severe driving conditions like stop and go driving around White Marsh, as well as in very hot or very cold conditions. More and more new vehicles are being delivered with full synthetic motor oil; with the recommendation to use synthetic for the life of the vehicle.
Why is this? Synthetic motor oil maximizes engine power and fuel economy. To see why; we’d need a microscope, so we’ll have to settle for using our imaginations.
The molecules of conventional motor oil are long hydrocarbon chains. Synthetic motor oil, on the other hand, has uniform, round molecules. Which is more slippery, a pile of pencils or a pile of marbles?
Synthetic motor oil lubricates better because there’s less friction. That means better wear protection, cooler operating temperatures, more power and better fuel economy. And synthetic oil doesn’t sludge up like conventional oil, so it prevents those small oil passages from clogging up.
Some manufacturers are extending oil change intervals. The added protection of synthetic oil covers you for these longer intervals. Talk with your service advisor about how you drive and see if he thinks you can benefit from synthetic oil. Also ask about the appropriate oil change interval for synthetic, because it may very well be longer than for conventional oil.
Most of us here in White Marsh have a busy life and might occasionally miss an oil change; go ahead admit it. Since we’re not perfect, doesn’t it make sense to use a motor oil that’s got your back?
Now synthetic oil costs more. But it lasts longer, protects better and increases fuel economy. You’ll likely save money in the long run. If you’re serious about making your car last longer, start using synthetic motor oil right away.
The price of gas has got everyone talking. It seems that people who need a bigger vehicle to carry family and gear, or provide four wheel drive, are especially hit hard. That is why we thought it would be good to review some things that anyone can do to improve fuel economy.
First let’s start with how we drive. People may not realize that they can really save on gas by just changing a few driving habits. One of the biggest is jackrabbit starts – you know, flooring the gas as soon as the light turns green. That really wastes a lot of fuel. Building up your speed at a slower pace uses less fuel and is easier on your engine and drive train. And don’t drive with one foot on the brake. That’s also a drag on fuel economy, and it wears out your brakes faster too.
Another thing is to drive slower – but only when it’s safe. Sometimes on the highway we drive an extra five … ten . . . twenty … over the speed limit. We do it to save time, but it only saves a few minutes out of maybe an hour long drive, and we may use 10 to 15 % more gas. Just leave a little bit earlier, save some money and arrive more relaxed.
You can also try and group all of your errands for the day into just one trip, rather than several. If you can put off a trip today that can be combined with one tomorrow – you can save some time and money.
Using your cruise control can save money too. Driving at a constant speed really improves fuel economy. Be sure to only use your cruise control under safe conditions – you can look in your owner’s manual for some good tips on using your cruise control.
Did you know that reducing the weight in your vehicle saves gas? Clean out the trunk or back seat from time to time so that you are not paying to carry around a lot of stuff you do not need in the car. If you live where there is snow and ice, clear it off your car. They add weight and mess with aerodynamics too.
Another tip is to avoid long idle times, which includes warming it up when you start. Modern engines do not require a long warm up to get going – just take it easy for a couple of miles.
Be sure to get a new gas cap if yours leaks or is worn.
Now, let’s start talking mechanical. Bottom line – the better you maintain your vehicle, the less fuel you will use. It all adds up in a big way. For example, replacing your dirty engine air filter will pay for itself in fuel savings before your next oil change – and will keep saving you money after that.
A clean, well-maintained fuel system really pays big dividends. A clogged fuel filter wastes gas. So does a dirty fuel system, grimy fuel injectors and plugged up PCV valves. A fuel system service decreases the gas you use, and increases the power – so you can’t go wrong with that.
Some of us ignore our Check Engine light. But fixing the problem that caused the light to come on will usually save some fuel as well. It may be a bad oxygen sensor that can really rob your fuel economy.
And, it may be time for a tune-up. Tune-ups should improve your fuel economy. Don’t overlook the routine maintenance items, like scheduled oil changes, transmission and cooling system service. Dirty or low fluids actually use more fuel. Just look at your manufacturer’s recommended service intervals in the owner’s manual, or ask your Quicklane Tire & Auto Center @ Al Packer White Marsh service advisor for the schedule.
Don’t forget your tires. Underinflated tires waste gas. And if your wheels are out of alignment you won’t get the economy you need.
None of these things are very complicated or expensive to stay on top of. When you maintain your car properly, you save gas today, and prevent costly repairs tomorrow.
Let’s focus on stopping in wet Middle River conditions. In order for a tire to have good contact with the road, it has to move the water out of the way. If it can’t move the water, the tire will actually ride on top of a thin film of water.
