Tires and wheels
Treadwear indicators
Narrow bands, sometimes called 
“wear bars” that show across the tread of 
a tire when only 
1/16in (1.6 mm) of tread 
remains.
TWR (T
ongue Weight Rating)
Maximum permissible weight on trailer 
tongue.
Uniform Tire Quality Grading Standards
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.
Vehicle capacity weight
Rated cargo and luggage load plus 
68 kilograms (150 lbs) times the vehicle’s 
designated seating capacity.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.Rotating tiresTire 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 a 
front-to-rear rotation pattern that will 
maintain the intended rotation (spinning) 
direction of the tire (page 255).
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.
If applicable to your vehicle’s tire configu-
ration, tires can be rotated according to 
the tire manufacturer’s recommended in-
tervals in the tire manufacturer’s warranty 
pamphlet located in your vehicle literature 
portfolio. If none is available, tires should 
be rotated every 3 000 to 6 000 miles 
(5 000 to 10 000 km), or sooner if neces-
sary, according to the degree of tire wear. 
The same rotation (spinning) direction 
must be maintained (
page 255). 
Warning!G
Rotate front and rear wheels only if the tires 
are of the same dimension.
If your vehicle is equipped with mixed-size 
tires (different tire dimensions front vs. 
rear), tire rotation is not possible.
