You should check air pressure regularly because tires function properly only when they have the correct level of air pressure. If the air pressure is low or high, tire function deteriorates, resulting in tire damage, and possibly an accident.
Manufacturers' recommended tire air pressure levels are indicated in your vehicle's user manual or on the inner part of the door. They vary slightly among various manufacturers.
Tips
- When driving for an extended period of time, it is recommended that the air pressure be upwardly adjusted by about 4 psi.
- Purchase a good pressure gauge and avoid often unreliable gas station gauges.
