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 5-69.
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 4-33.
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 Loading Your Vehicle on page 4-33.
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
