Jeep Grand Cherokee 2013 Operating Information Manual page 265

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 ca-
pacity at continuous speeds above 75 mph
(120 km/h).
Radial Ply Tires
WARNING!
Combining radial ply tires with other types of
tires on your vehicle will cause your vehicle
to handle poorly. The instability could cause
a collision. Always use radial ply tires in sets
of four. Never combine them with other types
of tires.
Cuts and punctures in radial tires are repairable
only in the tread area because of sidewall
flexing. Consult your authorized tire dealer for
radial tire repairs.
All Season Tires – If Equipped
All Season tires provide traction for all seasons
(spring, summer, fall and winter). Traction levels
may vary between different all season tires. All
season tires can be identified by the M+S, M&S,
M/S or MS designation on the tire sidewall. Use
all season tires only in sets of four; failure to do
so may adversely affect the safety and handling
of your vehicle.
Summer Or Three Season Tires – If
Equipped
Summer tires provide traction in both wet and
dry conditions, and are not intended to be
driven in snow or on ice. Summer tires will not
contain the all season designation or mountain/
snowflake symbol on the tire sidewall. Use
summer tires only in sets of four; failure to do so
may adversely affect the safety and handling of
your vehicle.
Snow Tires
Some areas of the country require the use of
snow tires during the winter. Snow tires can be
identified by a mountain/snowflake symbol on
the tire sidewall.
If you need snow tires, select tires equivalent in
size and type to the original equipment tires.
Use snow tires only in sets of four; failure to do
so may adversely affect the safety and handling
of your vehicle.
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 rec-
ommended 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.
