GMC 2007 Sierra - Manual (Page 563)

CAUTION: (Continued)
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 find traction devices that will fit,
install them on the rear tires.
Notice: If your vehicle does not have dual
wheels and is equipped with a tire size other
than P265/75R16, LT265/75R16, P265/70R17
or P275/55R20, 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. 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 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.
If a Tire Goes Flat
It is unusual for a tire to blowout while you are
driving, especially if you maintain your vehicle’s
tires properly. If air goes out of a tire, it is
much more likely to leak out slowly. But if you
should ever have a blowout, here are a few tips
about what to expect and what to do:
If a front tire fails, the flat tire will create a drag
that pulls the vehicle toward that side. Take
your foot off the accelerator pedal and grip the
steering wheel firmly. Steer to maintain lane
position, and then gently brake to a stop well out
of the traffic lane.
