(F) Uniform Tire Quality Grading (UTQG): Tire
manufacturers are required to grade tires based on
three performance factors: treadwear, traction, and
temperature resistance. For more information see
Uniform Tire Quality Grading on page 5-70.
(G) Maximum Cold Inflation Load
Limit
: Maximum load that can be carried and the
maximum pressure needed to support that load.
(A) Temporary Use Only
: The compact
spare tire or temporary use tire has a tread life of
approximately 3,000 miles (5 000 km) and should
not be driven at speeds over 65 mph (105 km/h).
The compact spare tire is for emergency use when
a regular road tire has lost air and gone flat. If your
vehicle has a compact spare tire, see Compact
Spare Tire on page 5-86 and If a Tire Goes Flat
on page 5-75.
(B) Tire Ply Material
: The type of cord and
number of plies in the sidewall and under the tread.
(C) Tire Identification Number (TIN)
: The letters
and numbers following the DOT (Department of
Transportation) code is the Tire Identification
Number (TIN). The TIN shows the manufacturer
and plant code, tire size, and date the tire was
manufactured. The TIN is molded onto both sides
of the tire, although only one side may have the
date of manufacture.
(D) Maximum Cold Inflation Load Limit
:
Maximum load that can be carried and the
maximum pressure needed to support that load.
(E) Tire Inflation
: The temporary use tire
or compact spare tire should be inflated to
60 psi (420 kPa). For more information on tire
pressure and inflation see Inflation - Tire Pressure
on page 5-58.
