Snow tires generally have lower speed ratings than
what was originally equipped with your vehicle and
should not be operated at sustained speeds over 75 mph
(120 km/h). For speeds above 75 mph (120 km/h), refer
to original equipment or an authorized tire dealer for
recommended safe operating speeds, loading and cold
tire inflation pressures.
While studded tires improve performance on ice, skid
and traction capability on wet or dry surfaces may be
poorer than that of non-studded tires. Some states
prohibit studded tires; therefore, local laws should be
checked before using these tire types.
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 infor-
mation.
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 recom-
mended tire rotation pattern.
