Tire rotation or rotating tires is the practice of moving automobile wheels and tires from one position on the car, to another, to ensure even tire wear. Tire wear is uneven for any number of reasons. Even tire wear is desirable to maintain consistent performance in the vehicle and to extend the overall life of a set of tires.

In the case of excessive tire wear, two new tires might be required.  The rule for replacing two worn tires is to always put new tires in the rear and rotate (if necessary) the partially worn tires to the front.  The video below shows examples of why:

During the snow storm, Snow Tires can make the difference between making it home or getting stuck

Winter driving can be a challenge, so ensuring a car’s tires are up to the task can give drivers extra piece of mind. In colder and snowier climes, using snow (or winter) tires may be a good idea for safety reasons.

Snow tires are different from the standard radials placed on cars, which are commonly referred to as “all season” tires. The tread plays a big part of this: the edges “bite” into the snow and ice better to give increased traction, and the rubber composition of the tire is softer.

This softer rubber allows the tire to be more flexible, which in turn prevents snow buildup between the tread. It also grips on ice better and provides more traction.

If your winter driving conditions are icy, then a studded tire may be the better option.  A studded tire is is essentially a tire with a metal stud added to the tread.  Studded tires provide excellent traction on icy, but at the expense of greater tire noise and road / driveway damage.

From a cost standpoint, studded tires will cost a bit more than snow tires and studded tires take longer to order.

Saturn Snow Traction Device

This year is predicted to be a COLD winter with lots of snow and ice!  Planning a head will save you lots of time and money.  Bernard’s Garage has cold weather tire solutions for just about any vehicle and driving circumstance.  Now is the time to decide if you will use:

• Studded Snow Tires
• Studless Snow Tires
• Tire Chains / Traction Device

Correct sizing is critical to prevent damage to the vehicle.  Tire size and wheel well spacing varies from one car to another.  In the State of Oregon, if your vehicle does not have studded tires, then you are required to carry snow chains or a traction device.  For example, Saturns have a plastic traction device that bolts to the outside of the wheel.

Tire Chains

Diamond tire chains pattern insures a comfortable ride with less vibration and  noise. Maximum traction with minimal brake distance and skidding. Alloy D-Links for extended life and traction.  Recommended for ABS and traction control systems.  Very easy, simple installation without the need to jack up, or move the car.

A good set of diamond chains run about $130 and are not returnable.

For some cars, the extra diameter of the chains is too great for the allowed space in the wheel well.  For that reason, diamond chains may not fit your vehicle.  You may need to use a cable chain or special made traction device (like the Saturn Device above.

Cable tire chains – The two primary materials used for winter traction devices are steel links and steel aircraft cable surrounded by steel rollers. Cable chains represent the latest evolution in winter traction devices. Lower-profile than link chains, cables fit more applications and offer a smoother ride. Because they’re lighter than links, cables are often easier to install, remove and store. Some even come packaged with rubber tighteners that eliminate having to stop and retighten the chains.

Cable tire chains are less expensive that Diamond chains, in the $60 price range.  While they are not as durable as the other snow chain options, they do meet the Oregon State snow chain requirement.  Installation of cable chains is critical!  Incorrect installation can cause serious damage to your fenders or drivetrain.

Bernard’s Garage Snow Tire University

OK, so it isn’t really a school, but if you buy snow chains from Bernard’s, we’ll teach you how to install them correctly.  We also have a snow tire installation kit available for $15.  The kit includes a piece of heavy carpet (to kneel on), a flashlight and a pair of waterproof gloves.

You car’s tires affect its ride, handling, traction and safety.  Tires are the critical connection between your car and the road in all sorts of driving conditions.

To maximize tire life and safety, check tire condition and inflation pressure regularly and have the tires rotated and balanced.  Tire replacement may be necessary if the tread depth is below the minimum legal requirement, or the sidewalls are severely cracked or punctured.  In some cases, tread punctures cannot be repaired.

Tire Service Checklist

• Check inflation pressure at least once a month (including the spare).
• Have the tires rotated every 6,000 miles.
• Rotation time also serves as a good opportunity to have the tires balanced.
• Uneven or accelerated tire wear may indicate an alignment problem.  Have you car’s alignment checked at least once a year.

Tire Inflation

What is it?

Proper tire inflation pressure is the specified air pressure given by a carmaker for a certain tire on a specific vehicle. This pressure specification should not be confused with a tire’s maximum pressure, which is usually listed on the tire’s sidewall. Some vehicles may specify different pressures for the front tires and the rear tires.

Purpose

Correct inflation pressure is critical for good fuel economy, safety, maximum tire life, and proper vehicle handling performance.

Maintenance Tips/Suggestions

For the small amount of time it takes, checking tire inflation at least once a month is one of the best investments you can make to get the maximum life out of your tires. Proper inflation can also improve gas mileage by more than 3%, when maintained regularly. Keep this in mind: Under-inflated tires can lower gas mileage by 0.4 percent for every 1 psi (pounds per square inch) drop in pressure of all four tires. You may want to check your tires more often during the winter months. Tires will lose about 1 psi of pressure for every 10 degrees Fahrenheit of temperature drop.

Keep an accurate tire pressure gauge in your car’s glove box (many gauges at “air stations” give false pressure readings) and check the tire pressure when the tires are cold. Never trust the appearance of a tire as a gauge for inflation. A tire could be 10 psi low on pressure and not appear to be low on air. Use the recommended inflation pressure listed in your vehicle’s owner’s manual or on the inflation sticker found on the driver’s door jamb. While you’re at it, don’t forget to check the spare. There’s nothing more annoying than a flat spare when you have a flat tire.

Tread Depth

What is it?

There are several simple ways to check tire tread depth. The first way is to measure tread depth with a tread depth gauge. The second method involves the use of a penny inserted into the grooves of the tread. Tire wear bars are also used on today’s tires as a hands-off visual indication that a tire needs replacement.

What does it do?

Regular tread depth checks are important to ensure that your car’s tires are safe. Excessive wear can result in a loss of traction, especially on wet and slippery roads. Tires are regular wear items and staying on top of their condition not only ensures your safety, but also gives you the opportunity to plan ahead and budget for inevitable tire replacement.

Maintenance Tips/Suggestions

When using a tread depth gauge, tires need to have at least 1/16-in. of tread or more (this is the minimum amount of tread allowed by law). By using a penny as a quick reference, insert the penny into the tread groove with Lincoln’s face showing, but with his head upside-down. If you are able to see all of Lincoln’s head, the tire needs replacement. If you see a wear bar across the width of the tread while facing it, it’s time to replace the tire. Generally, it’s best to replace tires in sets of four. If your car’s tires show signs of abnormal or unequal wear, have this looked into by a professional technician. Excessive wear on both outer edges generally indicates under-inflation. Excessive wear in the center of the tread generally indicates over-inflation. Cupping or dipping of certain tread sections may indicate worn suspension parts or a wheel balance problem. Saw-toothed or feathered tread edges may indicate wheel misalignment. If your car needs alignment or suspension work, have it done before you drive off with a new set of tires. Taking a “big picture” approach to protecting your tire investment will reap many rewards for miles to come.

Wheel Balance

Unbalanced wheels can cause rapid wear of shock absorbers and struts, and wheel balance can change as a result of normal tire wear.  On full-time four-wheel drive vehicles, a difference of only 1/4 inch between the outside circumference of the front and rear tires can cause expensive damage to the transfer case or center differential.  Rotating the tires to keep their sizes equal is critical on these vehicles, and replacing all four tires at the same time, rather than just the front or rear tires, is highly recommended.
