If 8 Goes FE&
It’s unusual for a tire to “blow out” while you’re driving,
especially
if you maintain your tires properly. If air goes
i...
...
out of a &e, it’s much moie 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: 1 ‘i
< 1 If a front tire fails, the flat tire will create a drag that
’, !! pulls the vehicle toward that side. Take YOLK foot off the g accelerator pedal and grip the steering wheel firmly.
P Steer to maintain lane position, and then gently brake to
-4 ,i a stop well out of the traffic lane.
.2? . A rear blowout, particularly on a cwe, acts much like a
skid and may require the same correction you’d use in a
8. Then replace the pressure cap. At any time during
this procedure if
CQQ~EUI~ begins to flow out of the
filler neck, reinstall the pressure cap. Be sure the
mows
on the pressure cap line up like this.
s~. h any kearblowout, remove your foot kom 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.
