Winter Tires

Tuesday, January 31st, 2012

What type of technology do you use? Do you prefer an 8-track tape or an iPod? When it comes to winter tires, much of the public’s perception dates back to when 8-track was the best way to listen to the Bee Gees.

Twenty years ago, winter tires differed from highway tires only in their tread design. We called them snow tires back then and they had big, knobby lugs that were designed to give good traction in deep snow. They had the same rubber compound as regular tires and they weren’t very good on ice, packed snow or wet roads. They were not even very good on dry roads. They really helped in deep or loose snow, but they did a poor job the rest of the time. They were loud and rode hard. You couldn’t wait to get them off in the spring.

Then all-season tires started to come along. All-season tires are really a compromise between summer and winter performance. They have acceptable hot weather ride and tread life, and you can get through mild winter road conditions OK. But there are some really good reasons to consider winter tires.

Modern winter tires do a terrific job in a wide range of winter conditions. First of all, below 45 degrees Fahrenheit, regular tires become hard and inflexible. That means they don’t provide the road grip you need. Even if you don’t live somewhere with a lot of snow, but it still gets below 45 degrees in the winter, you will be safer with winter tires.

In addition, they are specifically designed to more effectively move snow and water. That’s the key to traction on ice, packed snow and wet roads. They use a micro-pore compound that allows the tire to bite into ice and snow. They also use wider grooves that run around the circumference of the tread to expel snow from the tire better. The lugs and grooves on winter tires have a special shape that throws the packed snow out of the tread as the tire turns. The tread is then open when it comes back in contact with the road and can provide good traction.

Winter tires also have a lot of sipes. Sipes are thin slits in the tread. The edge of the sipes grab ice and packed snow to provide tons of traction and to expel water and slush out of the tread. winter tires have a rounder casing to cut into the snow’s surface. The treads on regular summer tires can actually get packed with snow instead and become very slick. winter tires offer 25% to 50% more traction than all-season tires. And when it comes to stopping power, all-season tires take 42% longer to stop than winter tires. Sometimes that’s the difference between getting home safely and spending the night in a snow bank.

Now back when the 8-track was king, you just put snow tires on the drive wheels. That worked out OK because the rubber compound was essentially the same. Now, winter tires provide so much more traction than all-season or summer tires, that there’s a huge difference between the traction at the front and rear ends of the car if you only put winter tires on the drive wheels.

For example: if you take a corner on an icy road and the rear end starts to slide out, essentially the rear is trying to pass the front because it’s going faster. If you have high traction winter tires only on the front, they are going to be much more effective at transferring cornering grip and stopping power to the front wheels. This will actually cause the rear end to whip out even more.

That’s why tire manufactures instruct their dealers that they must install winter tires on the rear wheels as well whenever they put winter tires on the front end of any vehicle. It’s a major safety concern. It’s strongly recommended that winter tires be installed on all four wheels on rear wheel drive vehicles as well. The front tires do most of the steering and braking work – it only makes sense that you provide the front end with the best traction you can.

People often assume that if they have four-wheel drive or all-wheel drive they don’t need winter tires on all four wheels. Would you intentionally disconnect the four-wheel drive in poor road conditions? Of course you wouldn’t, but that’s essentially what you do if you only put winter tires on one end. It only makes sense to have the same level of traction and control at all four corners.

The province of Quebec in Canada has issued a law requiring all passenger vehicles, taxis and rental cars with Quebec license plates to install a full set of four winter tires between November 15th and April 1. It’s that important.

Many modern cars have traction control and anti-lock brakes so people may think that they don’t need winter tires. But you need traction to accelerate, steer and stop. The tires provide the traction so that the traction control and anti-lock brakes have something to work with.

Look for tires with the symbol of a mountain with a snowflake in it. This means the tire complies with the severe snow standard. All-season tires will have an M&S, for mud and snow, on the sidewall.

So when the temperatures drop below 45 degrees, be sure you have a set of four winter tires for maximum performance in snow, packed snow, ice, wet and dry roads. Your tire professional can help you find the right winter tire for your vehicle and driving needs.

Quicklane Tire & Auto Center @ Al Packer White Marsh Tire Safety: Washington vs. Lincoln

Tuesday, January 24th, 2012


  />  

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.

Quicklane Tire & Auto Center @ Al Packer White Marsh Tire Safety Washington vs. LincolnLet’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.

Wheel Balancing

Tuesday, January 17th, 2012

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

Severe Service Requirements

Tuesday, January 10th, 2012

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.

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.

Check your owners’ manual for any other recommended service and have Quicklane Tire & Auto Center @ Al Packer White Marsh do the multi-point inspection before you head out.

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.
