Compact Spare T,ire
Although the compact spare was fully inflated when
your vehicle -was new, it can lose air after a time. Check
the inflation pressure regularly. It should be
60 psi (420
Pa). The compact spare is made to g6 up to 3,000 miles
(50,OO km), so you can finish your trip and have. your
full-size tire repaired
or replaced where you want. Of
course, it’s best to replace your spare with a full-size ti\
re
as soon as you can. Your spare will last longer and be in
good shape in case you need it again.
Your anti-1ock.brake system warning light -may come on
when you are driving with a compact spare. See
“Anti-Lock Brake System Waming Light”
in the Index.
Don’t-use
your compact spare on some other vehicle. And don’t mix your compact spare or wheel
with other
wheels or tires. They. won’t
fit.. Keep your spare and its
wheel together.
