when tested under controlled condi‐
tions on a specified indoor laboratory
test wheel. Sustained high tempera‐
ture can cause the material of the tire
to degenerate and reduce tire life, and
excessive temperature can lead to
sudden tire failure. The grade C cor‐
responds to a level of performance
which all passenger car tires must
meet under the Federal Motor Vehicle
Safety Standard No. 109. Grades
B and A represent higher levels of
performance on the laboratory test
wheel than the minimum required by
law.
If a tire goes flat
It's unusual for a tire to "blowout"
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 cre‐
ate a drag that pulls the vehicle to‐
ward that side. Take your foot off the
accelerator pedal and grip the steer‐
ing 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'd use in a skid. In any rear blow‐
out, remove your foot from the accel‐
erator 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.
Loading your vehicle
This is an example of what your vehi‐
cle's Tire-Loading Information/Certifi‐
cation label might look like. It is loca‐
ted on the B-pillar and shows how
much weight your vehicle may prop‐
erly carry. The label tells you the
proper size, and recommended infla‐
tion pressures for the tires on your ve‐
hicle. It also gives you important in‐
formation about the number of people
that can be in your vehicle and the to‐
tal weight that you can carry. This
weight is called the Vehicle Capacity
