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. See

Uniform

Tire Quality Grading on page 421

.

Vehicle Capacity Weight:

The number of

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

Loading

Your Vehicle on page 319

.

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’s capacity
weight and the original equipment tire size and
recommended inflation pressure. See “Tire
and Loading Information Label” under

Inflation - Tire Pressure

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

Notice:

Do not let anyone tell you that

under-inflation or over-inflation is all right.
It is not. If your tires do not have enough air
(under-inflation), you can get the following:

•

Too much flexing

•

Too much heat

•

Tire overloading

•

Premature or irregular wear

•

Poor handling

•

Reduced fuel economy

If your tires have too much air (over-inflation),
you can get the following:

•

Unusual wear

•

Poor handling

•

Rough ride

•

Needless damage from road hazards
