See
When It Is Time for New Tires on page 416 .
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 419 .

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
