Compact Spare Tire - Buick Lucerne 2007 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,
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 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.
