SERVICE AND APPEARANCE CARE tration later in this section for more detail. Department of Transportation (DOT) Code The Department of Transportation (DOT) code indicates that the tire is in compliance with the U.S. Department of Transportation Motor Vehicle Safety Standards. Tire Identification Number (TIN) The letters and numbers following the DOT code are the Tire Identification Number (TIN). The TIN shows the manufacturer and plant code, tire size and the date the tire was manufactured. The TIN is molded on to both sides of the tire, although only one side may have the date of manufacture. Tire Ply Material The type of cord and number of plies in the sidewall and under the tread. Uniform Tire Quality Grading (UTQG) Tire manufacturers are required to grade tires based on three performance factors: treadwear, traction and temperature resistance. Maximum Cold Inflation Load Limit Maximum load that can be carried and the maximum pressure needed to support that load. Load Index and Speed Rating The two- or three-digit number is the tire's load index, the maximum load a tire can carry at the speed indicated by its speed symbol at the maximum inflation pressure. The higher the number is, the greater the load carrying capacity. The letter symbol denotes the speed at which a tire is designed to be driven for extended periods of time. (Ratings are listed below.) Letter Rating Q R S T U H V W Y Speed Rating 99 mph 106 mph 112 mph 118 mph 124 mph 130 mph 149 mph 168 mph* 186 mph* A. Temporary Use Only Marking The compact spare tire should not be driven at speeds over 50 mph (80 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" and "If a Tire Goes Flat" in this section. B.

B. Department of Transportation (DOT)
Code
The Department of Transportation
(DOT) code indicates that the tire is in
compliance with the U.S. Department
of
Transportation
Motor
Vehicle
Safety Standards.
C. Tire Identification Number (TIN)
The letters and numbers following the
DOT code are the Tire Identification
Number (TIN). The TIN shows the
manufacturer and plant code, tire size
and the date the tire was manufac-
tured. The TIN is molded on to both
sides of the tire, although only one
side may have the date of manufac-
ture.
D. Tire Ply Material
The type of cord and number of plies
in the sidewall and under the tread.
E. Uniform Tire Quality Grading (UTQG)
Tire manufacturers are required to
grade tires based on three perfor-
mance factors: treadwear, traction
and temperature resistance.
F. Maximum Cold Inflation Load Limit
Maximum load that can be carried
and the maximum pressure needed to
support that load.
G. Load Index and Speed Rating
The two- or three-digit number is the
tire’s load index, the maximum load a
tire can carry at the speed indicated
by its speed symbol at the maximum
inflation pressure. The higher the
number is, the greater the load carry-
ing
capacity.
The
letter
symbol
denotes the speed at which a tire is
designed to be driven for extended
periods of time. (Ratings are listed
below.)
*The letters ZR may be used on tires with a
maximum speed capability over 149 mph
and will always be used on tires with a
maximum speed capability over 186 mph.
Compact Spare Tire Example
A. Temporary Use Only Marking
The compact spare tire should not be
driven at speeds over 50 mph (80 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” and “If a Tire
Goes Flat” in this section.
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 Tire Identification Number (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.
