== Calculating Rolling Radius from RPM or RPK ==
To get a correct rolling radius for accurate performance, it is possible to use the Revolutions per Mile (RPM) or per Kilometer (RPK) figure published by the tire manufacturer. This is used to set the position of the ''bb'' locator in the wheel model.
===From RPM===
The rolling radius in meters is given by:
r<sub>rolling</sub> = 1609.34 ÷ ( RPM × 2 × π )
===From RPK===
The rolling radius in meters is given by:
r<sub>rolling</sub> = 1000 ÷ ( RPK × 2 × π )
