Compact Spare Tire
Although the compact spare tire was fully inated
when the vehicle was new, it can lose air after
a time. Check the ination pressure regularly. It
should be 60 psi (420 kPa).
After installing the compact spare on the vehicle,
you should stop as soon as possible and make
sure the spare tire is correctly inated. 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 nish your trip
and have the full-size tire repaired or replaced
where you want. You must calibrate the tire
ination monitor system after installing or removing
the compact spare. SeeTire Pressure Monitor
System on page 433. The system may not
work correctly when the compact spare is installed
on the vehicle. Of course, it’s best to replace
the spare with a full-size tire as soon as you can.
The spare will last longer and be in good shape
in case you need it again.Notice:When the compact spare is installed,
do not take your vehicle through an automatic
car wash with guide rails. The compact
spare can get caught on the rails. That can
damage the tire and wheel, and maybe
other parts of your 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 t.
Keep the spare tire and its wheel together.
Notice:Tire chains will not t your compact
spare. Using them can damage your vehicle
and can damage the chains too. Do not use tire
chains on your compact spare.
