Checking Tire Inflation Pressure

Always check tire inflation pressure using an accurate pressure gauge. Never inflate the tires to levels above or below the recommended pressure. Tire inflation pressures are carefully calculated to give the vehicle satisfactory ride and steering characteristics, without compromising tire tread life.
 

The recommended vehicle load capacities and tire inflation pressures for full or reduced load operation are listed on the Tire Size and Inflation Pressure Chart. This chart is provided in the Owner Guide and on a label attached to the passenger door B-pillar.
 

Check and adjust tire inflation pressure only when the tires are cold (after the vehicle has been parked for at least three hours), or after the vehicle has been driven less than 3.2 km (2 miles) at speeds less than 64 km/h (40 mph).

Do not reduce the tire inflation pressure when the tires are hot, or after the vehicle has been driven over 3.2 km (2 miles) at speeds in excess of 64 km/hr (40 mph). Under such conditions, pressures can increase as much as 41 kPa (6 psi) over cold inflation pressures.

After checking or adjusting the tire inflation pressures, make certain to install the tire valve stem caps. The caps help prevent air leaks and keep dust and dirt out of the valve stems.

Check the valve stems. If any valve stem is worn, cracked, loose, or leaking air, replace it.

CAUTION:
Radial-ply tires have highly flexible sidewalls which produce a noticeable sidewall bulge, making the tires appear underinflated. This is a normal condition for radial-ply tires. Do not attempt to eliminate this bulge by overinflating the tires.
