Tire Chains

Warning
If the vehicle has 225/40R18,
225/40RF18, 255/35RF18, 225/
35R19, or 255/30R19 size tires,
do not use tire chains. 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 loss of
control and a crash. Use another
type of traction device only if its
manufacturer recommends it for
the vehicle's tire size combination
