Treadwear Indicators: Narrow bands, sometimes
called wear bars, that show across the tread of
a tire when only 1/16 inch (1.6 mm) of tread
remains. See When It Is Time for New Tires on
page 5-72.
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 5-75.
Vehicle Capacity Weight

designated seating positions multiplied by 150 lbs
(68 kg) plus the rated cargo load. See Loading

: 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

System (TPMS) is used to alert you if a tire has
lost pressure.

When the low tire warning light is displayed on
the instrument panel cluster, your vehicle’s
handling capabilities will be reduced during
severe maneuvers. If you drive too fast, you
could lose control of your vehicle. You or
others could be injured. Do not drive over
55 mph (90 km/h) when the low tire warning
light is displayed. Drive cautiously and check
your tire pressures as soon as you can.
If a tire goes flat, you will not need to stop on the side
of the road to change the tire. You can just keep on

slower the speed, the greater the chance that the tire
will not have to be replaced. If you drive on a deflated
