Tires and wheels
& Types of tires
You should be familiar with type of tires
present on your vehicle.
! All season tires
The factory-installed tires on your new
vehicle except 2.5 L turbo models 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
conditions. However all season tires do
not offer as much traction performance as
winter (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.
! Summer tires
The factory-installed tires on your new 2.5
L turbo models are 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-
covered 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
replace all four tires.
! 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
summer tires and all season tires on roads
other than snow-covered and icy roads.
& Tire pressure monitoring
system (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
vehicle 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 illuminate. To avoid this
problem when adjusting the tire pressures
in a warm garage, inflate the tires to
pressures 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
every difference of 10 8F (5.68C) between
the temperature in the garage and the
temperature 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
8F (15.68C).
Example:
Tire size: P215/70R16 99S, P225/60R17
98T
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 8F (15.68C)
