If a Tire Goes Flat
It is unusual for a tire to blowout while you are
driving, especially if you maintain your 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.
A rear blowout, particularly on a curve, acts much
like a skid and may require the same correction
you would use in a skid. In any rear blowout,
remove your foot from the accelerator pedal. Get
the vehicle under control by steering the way
you want the vehicle to go. It may be very bumpy
and noisy, but you can still steer. Gently brake
to a stop –– well off the road if possible.
If a tire goes flat, avoid further tire and wheel
damage by driving slowly to a level place and turn
on your hazard warning flashers. See
Hazard
Warning Flashers on page 140 .

CAUTION:
Your vehicle, when new, did not include
tire changing equipment or a place to
store a tire in the vehicle. Special tools
and procedures are required if a tire
needs to be serviced. If these tools and
procedures are not used, you or others
could be injured or killed while trying to
change or service a truck tire.
Your truck, when new, did not include tire changing
equipment or a place to store a tire in the
vehicle. Few drivers of these vehicles have the
necessary equipment aboard to be able to change
a flat tire safely. For example, you would need
a truck jack that can lift several thousand pounds
and a torque wrench that can generate several
hundred foot-pounds (
Y ) of twisting force.
