Spare Tire
Compact Spare Tire
{ WARNING:
Driving with more than one compact spare tire
at a time could result in loss of braking and
handling. This could lead to a crash and you or
others could be injured. Use only one compact
spare tire at a time.
This vehicle may have a compact spare tire. Although the
compact spare tire was fully inflated when the vehicle
was new, it can lose air after a time. Check the inflation
pressure regularly. It should be 60 psi (420 kPa).
After installing the compact spare on the vehicle, stop
as soon as possible and make sure the spare tire
is correctly inflated. The compact spare is made to
perform well at speeds up to 65 mph (105 km/h)
for distances up to 3,000 miles (5 000 km), so you can
finish your trip and have the full-size tire repaired or
replaced at your convenience. Of course, it is best
to replace the spare with a full-size tire as soon as
possible. The spare tire will last longer and be in good
shape in case it is needed again.
Notice: When the compact spare is installed, do
not take the vehicle through an automatic car wash
with guide rails. The compact spare can get
caught on the rails which can damage the tire,
wheel and other parts of the vehicle.
Do not use the compact spare on other vehicles.
And do not mix the compact spare tire or wheel with
other wheels or tires. They will not fit. Keep the
spare tire and its wheel together.
Notice: Tire chains will not fit the compact spare.
Using them can damage the vehicle and can damage
the chains too. Do not use tire chains on the
compact spare.
