TIRE PRESSURE

Air is a gas, expanding when heated and contracting when cooled. For most of North America, fall and early winter are especially important times for checking tire pressure on your Chevrolet, GMC, Buick vehicle. As the ambient temperature falls, tire pressure goes down. A good rule of thumb: with every 10 degrees Fahrenheit of temperature change, tire pressure changes about 1 psi–higher as temperatures rise, lower as they fall.

UNDERSTANDING THE TIRE PRESSURE MONITORING SYSTEM (TPMS)

The Tire Pressure Monitoring System (TPMS) helps with keeping you updated on the vehicle’s tire pressure. The TPMS works by sending a signal from the pressure sensor, located in your vehicle’s wheel, to the instrument control panel which alerts you when the tire pressure is low. It is recommended that a trained professional inspect and, if necessary, service your TPMS to help ensure it is working properly.

INDICATION THAT AIR PRESSURE IS LOW OR TPMS HAS MALFUNCTIONED

If the Tire Pressure Monitor light illuminates and stays solid with a Check Tire Pressure, Low Tire Pressure, or Add Air to Tire message, check and adjust all tire air pressures to the recommended levels.

If the Tire Pressure Monitor light appears as a blinking yellow lamp for more than one minute and stays solid, diagnostic service is needed.

SPEED RATINGS

Tire Ratings

WHAT ARE TIRE SPEED RATINGS?

Tire speed ratings indicate the speed your tire can safely maintain over time. The U.S. Department of Transportation (DOT) set the ratings scale below. On the sidewall of every tire, you’ll find one of these tire speed rating codes below:

TYPES OF TIRE WEAR

There are many factors that can cause tire wear such as your driving style and tire maintenance habits. Tire replacement is absolutely needed when the tread wear indicators appear. A tire’s built-in tread wear indicators look like narrow strips of smooth rubber across the tread and become visible as the tire surface wears.

TIRE ROTATION AND ALIGNMENT

Tire Wear

WHEN SHOULD TIRES BE ROTATED?

Tire rotation is the practice of moving your vehicle’s wheels and tires from one position to another to help promote even tire wear. Even tire wear can help with the life of your vehicle’s tires. It is important to rotate your tires at the intervals recommended by your Owner’s Manual.

DO I NEED A WHEEL ALIGNMENT?

If your vehicle is misaligned, it can cause your tires to wear unevenly, and you may experience handling problems such as pulling or abnormal vibration.

Tires and wheels are aligned and balanced at the factory to help provide the best overall performance. Consider a wheel alignment check if there is unusual tire wear or if your vehicle is significantly pulling to one side or the other.

A tire that is out of balance often affects ride quality and can shorten the life of tires, shocks, and other suspension components. If the vehicle vibrates when driving on a smooth road, the tires may need to be rebalanced.
