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 5-66.
Vehicle Capacity Weight
: The number of
designated seating positions multiplied by 150 lbs
(68 kg) plus the rated cargo load. See Loading
the Vehicle on page 4-16.
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
the Vehicle on page 4-16.
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
A vehicle specific Tire and Loading Information
label is attached to your vehicle. This label shows
your vehicle’s original equipment tires and the
correct inflation pressures for your tires when they
are cold.
