(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 5-79.
(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
:
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 5-104 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 5-66.
