Chevrolet Equinox Owners Manual: Tire Pressure

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

Caution 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. See Vehicle Load Limits.

How the vehicle is loaded affects vehicle handling and ride comfort. Never load the vehicle with more weight than it was designed to carry.

When to Check

Check the tires once a month or more. Do not forget the compact spare, if the vehicle has one.

The cold compact spare tire pressure should be at 420 kPa (60 psi). See Compact Spare Tire.

How to Check

Use a good quality pocket-type gauge to check tire pressure.

Proper tire inflation cannot be determined by looking at the tire.

Check the tire inflation pressure when the tires are cold, meaning the vehicle has not been driven for at least three hours or no more than 1.6 km (1 mi).

Remove the valve cap from the tire valve stem. Press the tire gauge firmly onto the valve to get a pressure measurement.

If the cold tire inflation pressure matches the recommended pressure on the Tire and Loading Information label, no further adjustment is necessary.

If the inflation pressure is low, add air until the recommended pressure is reached. If the inflation pressure is high, press on the metal stem in the center of the tire valve to release air.

Recheck the tire pressure with the tire gauge.

Put the valve caps back on the valve stems to keep out dirt and moisture and prevent leaks. Use only valve caps designed for the vehicle by GM. TPMS sensors could be damaged and would not be covered by the vehicle warranty.

Tire Terminology and Definitions
Air Pressure : The amount of air inside the tire pressing outward on each square inch of the tire. Air pressure is expressed in kPa (kilopascal) or psi (pounds per square inch). Accessory Weig ...

Tire Pressure Monitor System
The Tire Pressure Monitor System (TPMS) uses radio and sensor technology to check tire pressure levels. The TPMS sensors monitor the air pressure in your tires and transmit tire pressure readings ...
