Run Flat Tires — If Equipped
Run Flat tires allow you the capability to drive 50 miles (80 km) at 50 mph (80 km/h)
after a rapid loss of inflation pressure. This rapid loss of inflation is referred to as the
Run Flat mode. A Run Flat mode occurs when the tire inflation pressure is of/or below
14 psi (96 kPa). Once a Run Flat tire reaches the Run Flat mode, it has limited driving
capabilities and needs to be replaced immediately. A Run Flat tire is not repairable.
It is not recommended to drive a vehicle loaded at full capacity, or to tow a trailer
while a tire is in the Run Flat mode.
See the tire pressure monitoring section for more information.
Spare Tires — If Equipped
NOTE:
For vehicles equipped with Tire Service Kit instead of a spare tire, please refer to the
“Tire Service Kit” section located in your Owner’s Information kit for further
information.
CAUTION!
Because of the reduced ground clearance, do not take your vehicle through an
automatic car wash with a compact or limited use temporary spare installed.
Damage to the vehicle may result.
Spare Tire Matching Original Equipped Tire And Wheel — If Equipped
Your vehicle may be equipped with a spare tire and wheel equivalent in look and
function to the original equipment tire and wheel found on the front or rear axle of
your vehicle. This spare tire may be used in the tire rotation for your vehicle. If your
vehicle has this option, refer to an authorized tire dealer for the recommended tire
rotation pattern.
Compact Spare Tire — If Equipped
The compact spare is for temporary emergency use only. You can identify if your
vehicle is equipped with a compact spare by looking at the spare tire description on
the Tire and Loading Information Placard located on the driver’s side door opening or
on the sidewall of the tire. Compact spare tire descriptions begin with the letter “T”
or “S” preceding the size designation. Example: T145/80D18 103M.
T, S = Temporary Spare Tire
Since this tire has limited tread life, the original equipment tire should be repaired
(or replaced) and reinstalled on your vehicle at the first opportunity.
