20-Inch Tires

If your vehicle has the optional 20-inch
P275/55R20 size tires, they are classified as
touring tires and are designed for on road use. The
low-profile, wide tread design is not recommended
for “off-road” driving or commercial uses such
as snow plowing. See

Off-Road Driving on

page 372

and

Adding a Snow Plow or Similar

Equipment on page 416

for additional information.

Tire Sidewall Labeling

Useful information about a tire is molded into the
sidewall. The following illustrations are examples
of a typical P-Metric and a LT-Metric tire sidewall.

(A) Tire Size:

The tire size code 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.
