Tire Chains
{CAUTION:
If your vehicle has P205/55R16 or P205/50R17
size tires, do not use tire chains. They can
damage your vehicle because there is not
enough clearance.
Tire chains used on a vehicle without the
proper amount of clearance can cause damage
to the brakes, suspension, or other vehicle
parts. The area damaged by the tire chains
could cause you to lose control of your vehicle
and you or others may be injured in a crash.
Use another type of traction device only
if its manufacturer recommends it for use on
your vehicle and tire size combination, and
road conditions. Follow that manufacturer’s
instructions. To help avoid damage to your
vehicle, drive slowly, readjust, or remove
the device if it is contacting your vehicle,
and do not spin your vehicle’s wheels.
If you do nd traction devices that will t,
install them on the front tires.Notice:If your vehicle has a tire size other than
P205/55R16 or P205/50R17 size tires, use tire chains
only where legal and only when you must. Use
only SAE Class S-type chains that are the proper
size for your tires. Install them on the front tires and
tighten them as tightly as possible with the ends
securely fastened. Drive slowly and follow the chain
manufacturer’s instructions. If you can hear the
chains contacting your vehicle, stop and retighten
them. If the contact continues, slow down until
it stops. Driving too fast or spinning the wheels with
chains on will damage your vehicle.
