If a Tire Goes Flat
It's unusual for a tire to "blow out" while you're driving, especially if you
maintain your tires properly.
If
air goes out of a tire, it's 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, 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'd 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, the next part shows how to use your jacking equipment to
change a flat tire safely.
Changing a Flat Tire
If a tire goes flat, avoid further tire and wheel damage by driving slowly to a
level place. Turn on your hazard warning flashers.
