10-56 Vehicle Care
20‐Inch Tires
If the vehicle has 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 9‑7
and Adding a Snow Plow or
Similar Equipment on
page 9‑117 for additional
information.
Notice: Low‐profile tires
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 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 the sidewall.
The examples show a typical
