TiresAs your vehicles only contact point with the road below you, tires are easily one of the most important (and most overlooked) safety items on your vehicle.  Most drivers rarely consider the implications of poor tire maintenance until it comes time to replace a worn or damaged tire, or worse, when they’re sitting on the side of the road after having experienced a blowout.  Very few things can put a damper on your commute quite like changing a tire on the side of a busy highway. You don’t have to find yourself in this unpleasant situation; most tire failures can be avoided with proper maintenance.

Maintain the Correct Tire Pressure

Keeping your tires inflated to the manufacturer’s recommended pressure specification is your first line of defense against poor ride quality and premature tire wear. When your tires are over-inflated it reduces the tires ability to dampen road shock resulting in more stress on your vehicles suspension system and a rougher ride. Furthermore, over-inflation causes the edges of your tires to come up off of the road surface reducing the contact patch with the road. Not only will this lead to premature tire wear but it may also cause you to lose traction in wet or icy road conditions.

As confirmed on the television show MythBusters, under-inflation isn’t much better. Under-inflated tires have increased rolling resistance which makes your engine work harder and burn more fuel. They also bend more as they roll which causes more friction and builds internal heat, increasing the likelihood of sudden tire failure. With severely under-inflated tires you’ll likely notice a significant decrease of steering precision and stability when cornering. A 20% loss in tire pressure can reduce tread life by up to 25% and fuel economy by up to 5%. In most passenger cars, vans and light trucks that’s only about 7psi.

You should check all your tires (don’t forget the spare!) at least once a month and before any long trips. Even if you don’t see any damage, a healthy tire can lose 1-2 pounds of air pressure per month. For best results, you should check your tire pressure when they are cool – before driving the car or at least before going more than about 3 miles at low speeds. If this isn’t possible add 5 pounds to the recommended tire pressure to prevent under-inflation when they cool back down.

You can find the recommended tire pressure for your vehicle in the owner’s manual or on the tire placard usually located on the driver’s door or door jamb. It is important that you do not use the tire pressure printed on the sidewall of the tire. That number is the maximum tire inflation specification defined by the tire manufacturer and will usually be much higher than what your vehicle manufacturer recommends. If all else fails, call or stop by Parkhill Exxon and we’ll look up the inflation specs for your vehicle.

Check the pressure in your tires at least once a month. You can usually find the manufacturers recommended tire pressure on a yellow sticker in the driver’s door jamb.

Tire Rotations

When they design a suspension system, automotive engineers try to strike a balance between optimal tire wear and steering performance. These two considerations are usually at odds with each other; the best suspension geometry for steering performance and safety produces uneven and increased tire wear. That’s where tire rotations come in to play.

When you have your tires “rotated” the technician removes the tire and wheel assemblies from your vehicle and puts them back on in a different position. For example the front left tire might get moved to the rear right position. There are a few different rotation patterns that may be used depending on a number of variables, including the style of tire and type of vehicle you have.

Regardless of the rotation pattern the intent remains the same; to extend the service life of your tires. Tire rotations achieve this because, due to suspension geometry, portions of a tire’s tread aren’t used as much in some positions as they are in others. By changing the position a tire is in you allow more of the tread to be used over the life of the tire making it wear more evenly. A tire that wears evenly can last thousands of miles more than a tire that doesn’t which means improved reliability and less out of pocket expense for you.

Rotate your tires every 5,000 – 10,000 miles. The actual interval isn’t as important as making sure you stay consistent. We recommend getting this service every other oil change for most customers.

Wheel Balancing

Despite advances in the manufacturing process for both wheels and tires there is always going to be some fluctuation in material density, and therefore weight, in the finished product. Imbalances also develop over time due to the uneven tread wear. If left unchecked the resulting imbalances will cause vibrations that can be felt from inside the vehicle, especially at highway speeds. In the case of an extreme imbalance these vibrations can not only make for an uncomfortable ride but may lead to tire, wheel and suspension component damage.

A wheel is balanced by removing it from the vehicle and affixing it to a wheel balancing machine. The technician will input some information about the tire into the machine. The machine will then spin the tire at high speeds and sense any vibrations that may be present. If it senses an imbalance it will show the technician where to attach special wheel weights to cancel it out.
