Warning: The temperature grade f or
this tire is established f or a tire that
is properly inf lated and not
overloaded. Excessive speed,
underinf lation, or excessive loading, either separately or in combination,
can cause heat buildup and possible
tire f ailure.
Speed symbol (an
alphabetical code indicating
the maximum speed rating). Load index (a numerical code
associated with the maximum
load the tire can carry). Rim diameter in inches. Tire construction code (R
indicates radial).
Whenever tires are replaced, they
should be replaced with tires of the
same size. Following is an example
of tire size with an explanation of
what each component means. Aspect ratio (the tire’s section
height as a percentage of its
width). Tire width in millimeters. Vehicletype(Pindicates
passenger vehicle).
The tires that came on your vehicle
have a number of markings. Those
you should be aware of are described
below.
The temperature grades are A (the
highest), B, and C, representing the
tire’s resistance to the generation of
heat and its ability to dissipate heat
when tested under controlled
conditions on a specif ied indoor
laboratory test wheel. Sustained high
temperature can cause the material
of the tire to degenerate and reduce
tire life, and excessive temperature
can lead to sudden tire f ailure. The
grade C corresponds to a level of
perf ormance, which all passenger
vehicle tires must meet under the
Federal Motor Vehicle Saf ety
Standard No. 109 and No. 139.
Grades B and A represent higher
levels of perf ormance on the
laboratory test wheel than the
minimum required by law. The tire identif ication number (TIN)
is a group of numbers and letters
that look like the f ollowing example
TIN.
Date of manuf acture. Tire type code. Manuf acturer’s
identification mark. This indicates that the tire
meets all requirements of
the U.S. Department of
Transportation.
