Storing a jack, a tire, or other equipment in the passenger

Compact Spare Tire
Although the compact spare was fully inflated when your vehicle\
was new, it
can lose air after a time. Check the inflation pressure regula\
rly. It should be
60 psi (420 kPa). The compact spare is made to go up to 3,000 miles
(5000 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 tire as soon as you can. Your spare
will last longer and be in good
shape in case you need
it again.
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.
Tire chains won’t fit your compact spare. Using them will d\

Mixing tires could cause you to lose control while driving. If you mix
tires
of different sizes or types (like radial and bias-belted tires) the
vehicle may not handle properly, and you could have a crash. Be

to use the same size and type tires on all wheels. I
It’s all right to drive with your compact spare, though. It was developed for
limited use on your vehicle.
Uniform Tire Quality Grading
The following information relates to the system developed by the United
States National Highway Traffic Safety Administration which grade\
s tires by
treadwear, traction and temperature performance. (This applies o\
nly
to
vehicles sold in the United States.)
Treadwear
The treadwear grade is a comparative rating based on the wear \
rate of the
tire when tested under controlled conditions on a specified governmen\
t test
course.
For example, a tire graded 150 would wear one and a half (142)
times as well on the government course as a tire graded 100. The relative
performance of tires depends upon the actual conditions
of their use,
however, and may depart significantly from the norm due to var\
iations in
driving habits, service practices and differences in road charac\
teristics and
climate.
Traction-A, B, C
The traction grades, from highest to lowest are: A, B, and C. They represent
the tire’s ability
to stop on wet pavement as measured under controlled
conditions on specified government test surfaces of asphalt and \
concrete.
A
tire marked C may have poor traction performance.
Warning: The traction grade assigned
to this tire is based on braking
(straight-ahead) traction tests and does not include cornering \
(turning) traction.
Temperatur+A, B, C
The temperature grades are A (the highest), B, and C, representing the tire’s
resistance
to the generation of heat and its ability to dissipate heat when
tested under controlled conditions on a specified indoor laborat\
ory test wheel. Sustained high temperature can cause the material of the tire
to degenerate
and reduce tire life, and excessive temperature can lead
to sudden tire
