If a Tire Goes Flat
It is unusual for a tire to “blow out” 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. See Tires on page 6-47 for additional
information.
Your vehicle, when new, had run-flat tires. This type
of tire can operate effectively with no air pressure,
so you will not 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.
