General:
Tire width
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 tire width 1 (୴ page 392) indicates
the nominal tire width in mm.
Aspect ratio
No letter preceding the size designation
(as illustrated above): Passenger car tire
based on European design standards.
The aspect ratio 2 (୴ page 392) 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.
