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 When It Is Time
for New Tires on page 10‑69.
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 10‑72.
Vehicle Capacity Weight :
The number of designated
seating positions multiplied by
68 kg (150 lbs) plus the rated
cargo load. See Vehicle Load
Limits on page 9‑14.
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 and Loading
Information Label” under Vehicle
Load Limits on page 9‑14.
Tire Pressure
Tires need the correct amount
of air pressure to operate
effectively.
Notice: 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.
