How to convert P255 30R24 to inches?

First of all, we need to divide 255 mm (width) by 25.4 (mm to inch conversion), which will give us a width of 10″. Then, 30% of the 10″ will result in 3″ sidewall.

To get the total height or tire diameter, we need to sum the 24″ rim diameter with two of the sidewall heights. It will result in a 30″ total tire diameter (or height).
