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. See
Tires on page 6-46 for additional information.
Your vehicle, when new, had run-flat tires. This type of
tire can operate effectively with no air pressure, so
you won't need to stop on the side of the road to change
a flat tire. You can just keep on driving. The shorter
the distance you drive and the slower the speed,
the greater the chance that the run-flat tire will not have
to be replaced. Run-flat tires perform so well without
any air that a Tire Pressure Monitor (TPM) is used
to alert you if a tire has lost pressure. See Run-Flat Tires
on page 6-52 and Tire Pressure Monitor System on
page 6-55.
