Compact Spare Tire - Cadillac 2008 SRX Owner's Manual

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,
you should 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 where you want. You must calibrate the tire
inflation monitor system after installing or removing the
compact spare. See Tire Pressure Monitor System
on page 5-61. 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 fit. Keep the
spare tire and its wheel together.
Notice: Tire chains will not fit your compact spare.
Using them can damage your vehicle and can
damage the chains too. Do not use tire chains on
your compact spare.
