Operation
Tires and wheels
The tire inflation pressure should be checked
regularly. Only adjust the tire inflation
pressure on cold tires. The tires can be
considered cold if the vehicle has been
parked for at least 3 hours or driven less than
1 mile (1.6 km). Depending on the ambient
temperature, the driving speed and the tire
load, the tire temperature changes. When the
tire temperature changes by 18‡ (10†), the
tire inflation pressure will change by
approximately 1.5 psi (0.1 bar). Keep this in
mind when checking tire inflation pressure on
warm tires and adjust the tire pressure only
if the tire inflation pressure is too low for the
current operating conditions. If you check the
tire inflation pressure when the tires are
warm, the reading will be higher than the cold
reading. This is normal. Do not let air out to
match the specified cold tire inflation
pressure. Otherwise, the tire will be
underinflated.
Follow recommended cold tire inflation
pressures listed on Tire and Loading
Information placard on the driver's door
B-pillar.
Keeping the tires properly inflated provides
the best handling, tread life and riding
comfort.

recommended cold tire inflation
pressures
The Tire and Loading Information placard lists
the recommended cold tire inflation
pressures for maximum loaded vehicle
weight. The tire inflation pressures listed
apply to the tires installed as original

Performance tire inflation pressure for
speeds up to 155 mph (250 km/h)
With the Performance tire inflation pressure
the tire achieves the best grip and offers the
highest level of ride comfort. Set the
