Tires and wheels
Types of tires
You should be familiar with type of tires
present on your vehicle.
T All season tires
The factory-installed tires on your new ve-
hicle are all season tires.
All season tires are designed to provide
an adequate measure of traction, handling
and braking performance in year-round
driving including snowy and icy road con-
ditions. However all season tires do not of-
fer as much traction performance as win-
ter (snow) tires in heavy or loose snow or
on icy roads.
All season tires are identified by “ALL
SEASON” and/or “M+S” (Mud & Snow) on
the tire sidewall.
T Summer tires
Summer tires are high-speed capability
tires best suited for highway driving under
dry conditions.
Summer tires are inadequate for driving
on slippery roads such as on snow-cov-
ered or icy roads.
If you drive your vehicle on snow-covered
or icy roads, we strongly recommend the
use of winter (snow) tires.
When installing winter tires, be sure to re-
place all four tires.
T Winter (snow) tires
Winter tires are best suited for driving on
snow-covered and icy roads. However
winter tires do not perform as well as sum-
mer tires and all season tires on roads oth-
er than snow-covered and icy roads.
Tire pressure monitoring sys-
tem (TPMS) (if equipped)
The tire pressure monitoring system pro-
vides the driver with a warning message
by sending a signal from a sensor that is
installed in each wheel when tire pressure
is severely low. The tire pressure monitor-
ing system will activate only when the ve-
hicle is driven. Also, this system may not
react immediately to a sudden drop in tire
pressure (for example, a blow-out caused
by running over a sharp object).
If you adjust the tire pressures in a warm
garage and will then drive the vehicle in
cold outside air, the resulting drop in tire
pressures may cause the low tire pressure
warning light to come on. To avoid this
problem when adjusting the tire pressures
in a warm garage, inflate the tires to pres-
sures higher than those shown on the tire
placard. Specifically, inflate them by an
extra 1 psi (6.9 kPa, 0.07 kgf/cm
2
) for ev-
ery difference of 10
°F (5.6°C) between the
temperature in the garage and the tem-
perature outside. By way of example, the
following table shows the required tire
pressures that correspond to various out-
side temperatures when the temperature
in the garage is 60
°F (15.6°C).
Standard tire pressures:
Front: 32 psi (220 kPa, 2.2 kgf/cm
2
)
Rear: 30 psi (210 kPa, 2.1 kgf/cm
2
)
Garage temperature: 60
°F (15.6°C)
If the low tire pressure warning light
comes on when you drive the vehicle in
cold outside air after adjusting the tire
pressures in a warm garage, re-adjust the
tire pressures using the method described
above. Then, increase the vehicle speed
to at least 20 mph (32 km/h) and check to
see that the low tire pressure warning light
