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 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.
Tire Chains (Traction
Devices)
Use of traction devices require sufficient
tire-to-body clearance. Follow these
recommendations to guard against
damage.
Note:
Traction device must be of proper
size for the tire, as recommended by
the traction device manufacturer
Use on Rear Tires Only
Due to limited clearance, the
following traction devices are
recommended:
For a 265/35R19 98V tire, use of a
zero-clearance snow traction device
recommended.
It is not possible to install traction
devices on 285/30R19 tires.
Caution!
To avoid damage to your vehicle or tires,
observe the following precautions:
Because of restricted traction device
clearance between tires and other
suspension components, it is important
that only traction devices in good condition
are used. Broken devices can cause
serious damage. Stop the vehicle
immediately if noise occurs that could
indicate device breakage. Remove the
damaged parts of the device before further
use.
Install device as tightly as possible and
then retighten after driving about ½ mile
(0.8 km).
Do not exceed 30 mph (48 km/h).
Drive cautiously and avoid severe turns
and large bumps, especially with a loaded
vehicle.
Do not drive for a prolonged period on
dry pavement.
Observe the traction device
manufacturer's instructions on the method
of installation, operating speed, and
conditions for use. Always use the
suggested operating speed of the device
manufacturer's if it is less than 30 mph
(48 km/h).
Do not use traction devices on a
compact spare tire.
