Installing improper tires on your
vehicle can affect handling and
stability. This can cause a crash
in which you can be seriously
hurt or killed.
Always use the size and type of
tires recommended in this
owner's manual.Wheel and Tire Specifications
Wheels:
18 x 7 1/2J (TPMS)
Tires:
P235/55R18 99V
See page 482 for information about
DOT Tire Quality Grading, and page
484 for tire size and labeling
information. Winter Driving
Tires marked
‘‘M + S’’ or ‘‘All
Season ’’on the sidewall have an all-
weather tread design suitable for
most winter driving conditions.
For the best performance in snowy
or icy conditions, you should install
snow tires or tire chains. They may
be required by local laws under
certain conditions.
Snow Tires
If you mount snow tires on your
vehicle, make sure they are radial
tires of the same size and load range
as the original tires. Mount snow
tires on all four wheels. The traction
provided by snow tires on dry roads
may be lower than your original tires.
Check with the tire dealer for
maximum speed recommendations.

Use the compact spare tire as a
temporary replacement only. Get
your regular tire repaired or
replaced, and put it back on your
vehicle as soon as you can.
Check the inflation pressure of the
compact spare tire every time you
check the other tires. It should be
inflated to:
60 psi (420 kPa , 4.2 kgf/cm
2)Follow these precautions:
●Never exceed 50 mph (80 km/h).●This tire gives a harsher ride and
less traction on some road
surfaces. Use greater caution while
driving.●Do not mount snow chains on the
compact spare tire.●Do not use your compact spare tire
on another vehicle unless it is the
same make and model.●After the flat tire is replaced with
the spare tire, the low tire
pressure/TPMS indicator stays on.
After several miles (kilometers)
driving with the spare, this
indicator begins to flash, then
stays on again. You will also see a
‘‘
CHECK TPMS SYSTEM ’’
message on the multi-information
display (see page 393).
Replace the tire when you can see
the tread wear indicator bars. The
replacement should be the same size
and design tire, mounted on the
same wheel. The spare tire is not
designed to be mounted on a regular
wheel, and the spare wheel is not
designed for mounting a regular tire.
