Treadwear Indicators

:

Narrow bands,

sometimes called wear bars, that show
across the tread of a tire when only
1.6 mm (1/16 in) of tread remains. See

UTQGS (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

:

The number

of designated seating positions
multiplied by 68 kg (150 lb) plus the
rated cargo load. See

Vehicle Maximum Load on the Tire

:

Load on an individual tire due to curb
weight, accessory weight, occupant
weight, and cargo weight.

Vehicle Placard

:

A label permanently

attached to a vehicle showing the
vehicle capacity weight and the original
equipment tire size and recommended
inflation pressure. See

Tire Pressure

Tires need the correct amount of air
pressure to operate effectively.

{

Warning

Neither tire underinflation nor
overinflation is good. Underinflated
tires, or tires that do not have
enough air, can result in:

.

Tire overloading and overheating,
which could lead to a blowout.

.

Premature or irregular wear.

.

Poor handling.

.

Reduced fuel economy.

(Continued)

Warning (Continued)

Overinflated tires, or tires that have
too much air, can result in:

.

Unusual wear.

.

Poor handling.

.

Rough ride.

.

Needless damage from road
hazards.

The Tire and Loading Information label
on the vehicle indicates the original
equipment tires and the correct cold
tire inflation pressures. The
recommended pressure is the minimum
air pressure needed to support the
vehicle's maximum load carrying
capacity. See

How the vehicle is loaded affects
vehicle handling and ride comfort.
Never load the vehicle with more
weight than it was designed to carry.
