315/50R22 — what does it mean?
- 315 stands for tread width in millimeters
- 50 is an aspect ration between the tread width and the sidewall in percents
- R means that the tire has a radial construction
- 22 is a wheel diameter (or rim) in inches
How to convert 315 50R22 to inches?
First of all, we need to divide 315 mm (width) by 25.4 (mm to inch conversion), which will give us a width of 12.4″. Then, 50% of the 12.4″ will result in 6.2″ sidewall.
To get the total height or tire diameter, we need to sum the 22″ rim diameter with two of the sidewall heights. It will result in a 34.4″ total tire diameter (or height).
