Inflation Guidelines

Properly inflated tires provide the best combination of handling, tread life, and comfort. Refer to the driver’s doorjamb label or the specifications see SPECIFICATIONS for the specified pressure.
Underinflated tires wear unevenly, adversely affect handling and fuel economy, and are more likely to fail from overheating.
Overinflated tires make your vehicle ride harshly, are more prone to road hazards, and wear unevenly.
Every day before you drive, look at each of the tires. If one looks lower than the others, check the pressure with a tire gauge.
Measure the air pressure when tires are cold. This means the vehicle has been parked for at least 3 hours, or driven less than 1 mile (1.6 km). If necessary, add or release air until the specified pressure is reached. If checked when hot, tire pressure can be as much as 4-6 psi (30-40 kPa, 0.3-0.4 kgf/cm2) higher than checked when cold.
At least once a month or before long trips, use a gauge to measure the pressure in all tires. Even tires in good condition can lose 1-2 psi (10-20 kPa, 0.1-0.2 kgf/cm2) per month.
