Jeep Wrangler: Tires — General Information / Tire Pressures For High Speed Operation
FCA advocates driving at safe speeds and
within posted speed limits. Where speed limits
or conditions are such that the vehicle can be
driven at high speeds, maintaining correct tire
inflation pressure is very important. Increased
tire pressure and reduced vehicle loading may
be required for high-speed vehicle operation.
Refer to an authorized tire dealer or original
equipment vehicle dealer for recommended
safe operating speeds, loading and cold tire
inflation pressures.
WARNING!
High speed driving with your vehicle under
maximum load is dangerous. The added strain
on your tires could cause them to fail. You
could have a serious collision. Do not drive a
vehicle loaded to the maximum capacity at
continuous speeds above 75 mph (120 km/h).
Proper tire inflation pressure is essential to the
safe and satisfactory operation of your vehicle.
Four primary areas are affected by improper tire
pressure:
Safety
Fuel Economy
Tread Wear
Ride Comfort and Vehicle Stability
