CAUTION (Continued)
Worn, old tires can cause
accidents. If your tread
is badly worn, or if your
tires have been damaged,
replace them.
See High-Speed Operation
on page 9-47 for inflation
pressure adjustment for
high speed driving.
Low-Profile Tires
If the vehicle has 225/40ZR18
or 215/45R18 size tires, they
are classified as low-profile
performance tires. These tires
are designed for very responsive
driving on wet or dry pavement.
You may also notice more
road noise with low-profile
performance tires and that they
tend to wear faster.
Notice: If the vehicle has
low-profile tires, they are
more susceptible to damage
from road hazards or curb
impact than standard profile
tires. Tire and/or wheel
assembly damage can occur
when coming into contact with
road hazards like, potholes,
or sharp edged objects,
or when sliding into a curb.
The vehicle warranty does not
cover this type of damage.
Keep tires set to the correct
inflation pressure and,
when possible avoid contact
with curbs, potholes, and
other road hazards.
Winter Tires
If the vehicle has 225/40ZR18 or
215/45R18 size tires, they are
classified as low-profile performance
tires. These tires are designed for
very responsive driving on wet or dry
pavement. If you expect to drive
on snow or ice covered roads often,
you may want to get winter tires
for your vehicle. All season tires
provide good overall performance on
most surfaces but they may not
offer the traction you would like or
the same level of performance
as winter tires on snow or ice
covered roads.
Winter tires, in general, are
designed for increased traction on
snow and ice covered roads.
With winter tires, there may be
decreased dry road traction,
increased road noise, and shorter
tire tread life. After switching to
winter tires, be alert for changes in
vehicle handling and braking.
