Size Designation
EXAMPLE:P215/65R15
N
OTE
● European/Japanese metric tire sizing is based on
European/Japanese design standards. Tires designed
to these standards have the tire size molded into the
sidewall beginning with the section width. The letter
“P” is absent from this tire size designation. Exam-
ple: 215/65R15 96H.
● LT (Light Truck) -metric tire sizing is based on
U.S.A. design standards. The size designation for
LT-metric tires is the same as for P-metric tires
except for the letters “LT” that are molded into the
sidewall preceding the size designation. Example:
LT235/85R16.
● Temporary spare tires are high pressure compact
spares designed for temporary emergency use only.
Tires designed to this standard have the letter “T”
molded into the sidewall preceding the size designa-
tion. Example: T145/80D18 103M.

Load index
A numerical code associated with the maxi-

A symbol indicating the range of speeds at
which a tire can carry a load corresponding to
its load index under certain operating condi-

sure, vehicle loading, road conditions and
posted speed limits)

Use tires of the recommended load capacity for
