Tire width
The tire width 2 indicates the nominal
tire width in mm.
Aspect ratio
The aspect ratio 3 is the dimensional
relationship between tire section height
and section width and is expressed in
percentage. The aspect ratio is arrived
at by dividing section height by section
width.
Tire code
The tire code 4 indicates the tire con-
struction type. The “R” stands for radial
tire type. Letter “D” means diagonal or
bias ply construction; letter “B” means
belted-bias ply construction.
Rim diameter
The rim diameter 5 is the diameter of
the bead seat, not the diameter of the
rim edge. Rim diameter is indicated in
inches (in).
Tire load rating
The tire load rating 6 is a numerical
code associated with the maximum load
a tire can support.
For example, a load rating of 120 corre-
sponds to a maximum load of 3042 lbs
(1380 kg) the tire is designed to sup-
port.
If two values are given (as illustrated),
the first value, preceding the slash "/",
applies to single tires (rear axle). The
second value, succeeding the slash "/",
applies to twin tires (dual wheel rear ax-
le).
