GMC Terrain: Tire Pressure - Wheels and Tires - Vehicle Care - GMC Terrain Owner's ManualGMC Terrain: Tire Pressure

Tires need the correct amount of air pressure to operate effectively.

Notice: Neither tire underinflation nor overinflation is good. Underinflated tires, or tires that do not have enough air, can result in:

○ Tire overloading and overheating which could lead to a blowout.
○ Premature or irregular wear.
○ Poor handling.
○ Reduced fuel economy.

Overinflated tires, or tires that have too much air, can result in:

○ Unusual wear.
○ Poor handling.
○ Rough ride.
○ Needless damage from road hazards.

The Tire and Loading Information label on the vehicle indicates the original equipment tires and the correct cold tire inflation pressures. The recommended pressure is the minimum air pressure needed to support the vehicle's maximum load carrying capacity.

For additional information regarding how much weight the vehicle can carry, and an example of the Tire and Loading Information label, see Vehicle Load Limits on page 9‑16. How the vehicle is loaded affects vehicle handling and ride comfort. Never load the vehicle with more weight than it was designed to carry.
