Tyre Dimensions

We provide below some general information to help you read the tables:

S

Section width (in mm) of the unloaded tyre referring to the first of the rims shown in the table.
If the tyre is fitted on another of the rims shown in the list of permitted rims, the section width is obtained by decreasing (or increasing) the value shown in the table by 5 mm for every 0.5 variation in the width of the rim.

OD

Overall diameter of the tyre when inflated and unloaded.

Rstat

Static loaded radius: The distance between wheel centre and road surface, referring to a tyre inflated and loaded at the values shown in the table under static conditions.

Rc

Rolling circumference. Distance covered in one complete revolution of the drive wheel under the load and pressure conditions indicated in the table.

NOTE: The values in the tables are approximate, and may vary in practice, including a possible growth in service.
