10-50 Vehicle Care
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 manufacture rs using
government testing procedures.
The ratings are molded into the
sidewall of the tire. See Uniform
Tire Quality Grading on
page 10‑62.
Vehicle Capacity Weight
: The
number of designated seating
positions multiplied by
68 kg (150 lb) plus the rated
cargo load. See Vehicle Load
Limits on page 9‑11.
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 9‑11.
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.
Overinflated tires, or tires that
have too much air, can
result in:
.
Unusual wear.
.
Poor handling.
.
Rough ride.
.
Needless damage from
road hazards.
The Tire and Loading
Information label on the
vehicle indicates the original
equipment tires and the correct
cold tire inflation pressures. The
recommended pressure is the
minimum air pressure needed to
support the vehicle's maximum
load carrying capacity.
