Tire sizes for Sprinter vehicles
Design standard
Depending on the design standards used,
the tire size molded into the side wall may
have no letter or a letter 1 preceding the
tire width or the tire load rating designa-
tion.
Letter “LT” preceding the size designation:
Light Truck tire based on U.S. design stan-
dards.
Letter “C” preceding the tire load designa-
tion:
Commercial vehicle tire based on Europe-
an design standards.
Tire width
The tire width 2 indicates the nominal tire
width in mm.
Aspect ratio
The aspect ratio 3 is the dimensional re-
lationship between tire section height and
section width and is expressed in percent-
age. The aspect ratio is arrived at by divid-
ing 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 support.
If two values are given (as illustrated), the
first value, preceding the slash "/", applies
to single tires (rear axle). The second val-
ue, succeeding the slash "/", applies to
twin tires (dual wheel rear axle).
The commercial vehicle tires based on Eu-
ropean standards may have an additional
value in the parentheses (as illustrated). In
such cases, the value preceding the paren-
theses is valid for European countries and
the parenthesized for the USA and Canada.
Refer also to "Maximum tire load"
( page 226) where the maximum load as-
sociated with the load index is indicated in
kilograms and lbs.
