Tires and wheels
General:
Aspect ratio
Rim diameter
Depending on the design standards used,
the tire size molded into the sidewall may
have no letter or a letter preceding the tire
size designation.
The aspect ratio 2 (୴ page 261) 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.
The rim diameter 4 (୴ page 261) is the
diameter of the bead seat, not the
diameter of the rim edge. Rim diameter is
indicated in inches (in).
No letter preceding the size designation
(as illustrated above): Passenger car tire
based on European design standards.
Tire load rating
The tire load rating 5 (୴ page 261) is a
numerical code associated with the
maximum load a tire can support.
Tire code
Letter “P” preceding the size designation:
Passenger car tire based on U.S. design
standards.
The tire code 3 (୴ page 261) indicates
the tire construction type. The “R” stands
for radial tire type. Letter “D” means diag-
onal or bias ply construction; letter “B”
means belted-bias ply construction.
For example, a load rating of 91 corre-
sponds to a maximum load of 1356 lbs
Letter “LT” preceding the size designation:
Light Truck tire based on U.S. design
standards.
(615
kg) the tire is designed to support.
See also “Maximum tire load”
(୴ page 267) where the maximum load
associated with the load index is indicated
in kilograms and lbs.
At the tire manufacturer’s option, any tire
with a speed capability above 149 mph
Letter “T” preceding the size designation:
Temporary spare tires which are high
pressure compact spares designed for
temporary emergency use only.
(240
km/h) can include a “ZR” in the size
designation (for example: 245/40 ZR 18).
For additional information, see “Tire speed
rating” (୴ page 263).
Tire width
The tire width 1 (୴ page 261) indicates
the nominal tire width in mm.
