(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 6-75.
(G) Maximum Cold Inflation Load Limit
Maximum load that can be carried and the
maximum pressure needed to support that load.
Compact Spare Tire Example
(A) Temporary Use Only
:
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.
See "Compact Spare Tire" under Spare Tire on
:
page 6-101 for additional information.
(B) Tire Ply Material
number of plies in the sidewall and under
the tread.
(C) Tire Identification Number (TIN)
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
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 6-64.
