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 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.
What happens if your Chevrolet tire is underinflated?
What happens if your Chevrolet tire is overinflated?
Check your Chevrolet tires at least once a month when the tires are cold, meaning the vehicle has not been driven for at least three hours or no more than 1 mile. The Tire Information Label located on the inside of your vehicle’s doorframe has the recommended cold tire pressure for your vehicle. Use a quality gauge. Don’t try to eyeball it—radial tires may appear fine even when they’re underinflated. Look for objects that can get wedged in the tread—they’ll work themselves even further into the tire and cause air loss. To make sure you’re covered, every check of your tires should include a check of your spare (if available), as well.
The Tire Pressure Monitoring System (TPMS) on your Chevrolet vehicle is designed to warn the driver when low-tire-pressure conditions exist. A sensor measures tire pressure and temperature, then transmits data to the Tire Pressure Monitor. If the pressure in one or more of your tires is 25 percent or more below the vehicle manufacturer’s recommended cold inflation pressure for tires, a warning indication will alert the driver.
Your Original Equipment TPMS sensor battery can last up to 10 years with normal use. When the TPMS battery fails, the sensor will need to be replaced.
If the Tire Pressure Monitor light comes on and stays solid with a Check Tire Pressure, Low Tire Pressure, or Add Air To Tire message, then check and adjust all tire air pressures to the recommended levels. Next, drive the vehicle to turn the light off.
If the Tire Pressure Monitor light appears as a blinking yellow lamp for more than one minute and stays solid, then diagnostic service is needed. If your Chevrolet TPMS is not functioning properly, it cannot detect or signal a low-tire condition.
The road can be full of surprises for your tires. Stay up to date on your vehicle’s tire pressure with OnStar diagnostics reports. You’ll be notified when your tire pressure is low before it becomes a larger problem. If your eligible 2011 or newer vehicle is equipped with OnStar, but your account is inactive, push the blue OnStar button to reactivate service and we’ll give you 3 years of select OnStar services1 – no charge, no commitment, no kidding. Complimentary service includes OnStar Advanced Diagnostics and select myChevrolet mobile app features so you can conveniently control your vehicle features from your smartphone.2
The use of nitrogen gas to inflate tires is available through some dealers. Benefits under controlled conditions include:
Important: These are obtainable performance improvements when relatively pure nitrogen gas is used to inflate tires under controlled conditions.
Inflation pressure maintenance of tires is critical for overall tire and vehicle performance. Maintaining the correct inflation pressure allows the tire to perform as intended, including for comfort, fuel economy, stopping distance, cornering, traction, tread wear, and noise.
General Motors does not oppose the use of nitrogen gas in tires. We expect the theoretical benefits to be reduced in practical use due to the lack of an existing infrastructure to continuously facilitate inflating tires with nearly pure nitrogen. Even occasional inflation with compressed atmospheric air will negate many of the theoretical benefits. Given those theoretical benefits, practical limitations, and the robust design of GM Original Equipment TPC tires, the realized benefits to our customers of inflating their tires with purified nitrogen are expected to be minimal.
