Tire Chains
{CAUTION:
If your vehicle has P225/75R15, P265/75R15 or
P235/50R17 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
don’t spin your wheels.
If you do nd traction devices that will t,
install them on the rear tires.
Notice:If your vehicle has a tire size other than
P225/75R15, P265/75R15 or P235/50R17, use tire
chains only where legal and only when you must.
Use chains that are the proper size for your tires.
Install them on the tires of the rear axle. Do not use
chains on the tires of the front axle. 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.
