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:
Overinflated tires, or tires that have too much air, can result in:
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.
Return the valve caps on the valve stems to prevent leaks and keep out dirt and moisture.
Replacing Brake System Parts
The braking system on a vehicle is complex. Its many parts have to be of top
quality and work well together if the vehicle is to have really good braking. The
vehicle was designed and tested with top-quality brake parts. When parts of the
braking system are replaced, be sure to get new, approv ...
