Tire ply composition and material used
Treadwear indicators
Rotating tires
Warning!
This indicates the number of plies or the
number of layers of rubber-coated fabric in
the tire tread and sidewall. Tire manufac-
turers also must indicate the ply materials
in the tire and sidewall, which include
steel, nylon, polyester, and others.
Narrow bands, sometimes called
“wear bars” that show across the tread of
1
a tire when only /16 in (1.6 mm) of tread
remains.
G
Rotate front and rear wheels only if the tires
are of the same dimension.
TWR (Tongue Weight Rating)
If your vehicle is equipped with mixed-size
tires (different tire dimensions front vs.
rear), tire rotation is not possible.
Maximum permissible weight on trailer
tongue.
Tire speed rating
Part of tire designation; indicates the
speed range for which a tire is approved.
Uniform Tire Quality Grading Standards
Tire rotation can be performed on vehicles
with tires of the same dimension all
around. If your vehicle is equipped with
tires of the same dimension all around,
tires can be rotated, observing a
front-to-rear rotation pattern that will
maintain the intended rotation (spinning)
direction of the tire (୴ page 365).
A tire information system that provides
consumers with ratings for a tire’s traction,
temperature and treadwear. Ratings are
determined by tire manufacturers using
government testing procedures. The
ratings are molded into the sidewall of the
tire.
Total load limit
Rated cargo and luggage load plus
68
kilograms (150 lbs) times the vehicle’s
designated seating capacity.
Traction
Force exerted by the vehicle on the road
via the tires. The amount of grip provided.
In some cases, such as when your vehicle
is equipped with mixed-size tires (different
tire dimension front vs. rear), tire rotation
is not possible.
Vehicle maximum load on the tire
Load on an individual tire that is
determined by distributing to each axle its
share of the maximum loaded vehicle
weight and dividing it by two.
Tread
The portion of a tire that comes into
contact with the road.
