Low -profile tires can wear out faster than stand­
ard tires.
Summer tires are not su itable for cold weather,
snow or b lack ice. If you are driving in these con­
ditions, use winter or all season tires

pe rature
A .
All passenger car tires must conform to Federal
Safety Requirements in addition to these grades.
Tread w ear
The tread wear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified gov­
ernment test course.
F or example, a tire graded 150 would wear one
and one ha lf
(1 1/2) times as well on the govern­
ment course as a tire graded 100.
The relative performance of tires depends upon
the actual conditions of their use, however, and
may depart significant ly from the norm due to
variations in driving hab its, service practices and
d ifferences i n road characteristics and climate.
Tracti on
The traction grades, from highest to lowest, are
AA, A, Band
C. Those grades represent the tire's
ab ility to stop on wet pavement as measured un­
der controlled conditions on specified govern­
ment test surfaces of asphalt and concrete . A tire
marked C may have poor traction performance
¢ _& .
Temper ature
The temperature grades are A (the h ighest), B,
and C, representing the tire's resistance to the
Wh eel s
generat ion of heat and its ability to dissipate
heat when tested under controlled conditions on
a specified indoor laboratory test wheel.
Sustained h igh temperature can cause the mate­
ria l of the tire to degenerate and reduce tire life,
and excessive temperature can lead to sudden
tire
failure ¢.& .
The grade C corresponds to a level of per form ­
ance which all passenger car tires must meet un­
der the Federal Motor Vehicle Safety Standard
No. 109. Grades Band A represe nt higher levels
of performance on the laboratory test wheel than
the minimum requ ired by law.
A WARNING c,...._ -
The tract ion grade assigned to this t ire is
based on straight-ahead braking traction
tests, and does not include acceleration, co r­
nering, hyd roplaning or pea k traction cha rac­
terist ics.
A WARNING
The temperature grade for this tire is estab­
lished for a tire that is properly inflated and
not overloaded . Excessive speed, underinfla­
tion, or excessive loading, either separately or
i n comb inat ion, can cause heat bu ildup and
possib le tire fai lure.
A WARNING
-Temperature grades apply to tires that are
properly inflated and not over or under inflat­
ed.
Tire pressure monitoring system
ill General notes
Each tire, including the spare (if provided),
.
should be checked monthly when cold and inflat-
ed to the i nflat io n pressure recommended by the
vehicle manufacturer on the veh icle placard or
t ir e infla tion p ressure labe l. (If your ve hicle has
ti res of a different size t han t he si ze ind icated on

Emergency assistance
"'Secure the collapsible spare tire with the hand -
whee l.
"'Fo ld the cargo floor cover back into p lace.
Snow chains
Using snow chains on the collapsible spare tire is
not permitted for technical reasons.
If you have to drive with snow chains and a front
tire fa ils, mount the collapsible spare tire in
p la ce of a rear tire. Insta ll the snow cha ins on the
rear tire that you removed, and install that in
p lace of the front tire that failed.
A WARNING
-
- Only use the collapsible spare tire in emer ­
gencies and drive very carefully, especially if
it is more than six years old .
- The compressor and the hose can become
very hot during operation which increases
the risk of burn injuries.
- After installing a collapsible spare tire, the
t ir e pressure must be checked as quickly as
poss ible to reduce the risk of an acc ident.
- Do not drive faster than 50 mph (80 km/h)
with a collapsible spare tire. Driving faster
than that increases the risk of an accident .
- Avoid full-throttle acceleration, heavy brak­
ing, and fast cornering with the collapsible
spare tire, because this increases the risk of
an accident .
- Never drive using more than one collapsible
spare tire, because this increases the risk of
an accident.
- Normal tires or winter tires must not be
mounted on the collaps ible spare tire rim.
«J:) Note
The compressor must be switched off after 12
minutes at the most to reduce the risk of
overheating . Let the compressor cool down
for several minutes before using it again.
