Low-Profile Performance Tire
If your vehicle has P225/45R18 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.
Tire Sidewall Labeling
Useful information about a tire is molded into its
sidewall. The examples below show a typical
passenger vehicle tire and a compact spare tire
sidewall.
(A) Tire Size
: The tire size is a combination of
letters and numbers used to define a particular tire’s
width, height, aspect ratio, construction type, and
service description. See the “Tire Size” illustration
later in this section for more detail.
