Warning
If the vehicle has
235/40R18, 235/35R19,
255/35ZR18, or
275/35ZR18 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 and road
conditions. Follow that
manufacturer's instructions.
To avoid vehicle damage,
drive slow and readjust or
remove the traction device if

it contacts the vehicle. Do
not spin the wheels.
If traction devices are used,
install them on the rear tires.
Caution
If the vehicle is equipped
with a tire size other than
235/40R18, 235/35R19,
255/35ZR18, or
275/35ZR18, use tire chains
only where legal and only
when necessary. Use low
profile chains that add no
more than 12 mm thickness
to the tire tread and inner
sidewall. Use chains that are
the proper size for the tires.
Install them on the tires of
the rear axle. Don't 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
(Continued)
Caution (Continued)
chain manufacturer's
instructions. If the chains
contact the 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 the vehicle.
If a Tire Goes Flat
It is unusual for a tire to blow
out while driving, especially if
the tires are maintained
properly. If air goes out of a
tire, it is much more likely to
leak out slowly. See Tires
413 for additional
information. But if there ever
is a blowout, here are a few
tips about what to expect and
what to do:
If a front tire fails, the flat tire
creates a drag that pulls the
vehicle toward that side. Take
your foot off the accelerator
pedal and grip the steering
