Inflation Pressure
For tire pressure and maximum tire load rating specification values, refer to
tire loading information sticker located on rear edge of driver's side rear door.
The metric unit for tire inflation pressure is the kilopascal (kPa), although
inflation pressures are usually given in both kPa and psi. To convert between kPa
and psi, use the following conversion formula: 1 psi = 6.9 kPa
Important: Tire valve caps must always be installed onto the tire valve to keep dirt and
moisture out of valve.
Maintaining correct tire inflation pressure is essential to proper vehicle performance.
The specified inflation pressure is carefully calculated to provide satisfactory ride,
stability, precise steering, acceptable tire wear, and resistance to road damage.
Tire inflation pressure should be checked when tires are cold. Cold tires are
defined as tires on a vehicle that has not been driven for at least 3 hours
or more than 1 mile.
It is normal for the tire inflation pressure to increase 28 kPa (4 psi)
as vehicle is driven distances more than one mile, as the tires heat up. Therefore,
on a vehicle with warm tires, never attempt to correct tire pressure by letting air
out of the tire; wait until the tire cools down to check and adjust tire pressure.
Letting air out of a warm tire reduces cold inflation pressure.
Incorrect Tire Inflation Pressure
Incorrect tire inflation pressure can lead to the following symptoms:
Over-Inflation
• | Tire bruising or carcass damage |
• | Rapid tread wear at center of tire |
Under-Inflation
• | Rapid tread wear on tire edges |
• | Tire bruises or bead rupture |
