{CAUTION:
If your vehicle has P225/75R15, P265/
75R15, P235/75R15, or P235/50R18 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.

avoid damage to your vehicle, drive slowly,
readjust, or remove the device if it is
contacting your vehicle. Do not spin the
vehicle’s 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, P235/75R15 or
P235/50R18 use tire chains only where legal and
only when you must. Use chains that are the
