How to convert P205 40R16 to inches?

First of all, we need to divide 205 mm (width) by 25.4 (mm to inch conversion), which will give us a width of 8.1″. Then, 40% of the 8.1″ will result in 3.2″ sidewall.

To get the total height or tire diameter, we need to sum the 16″ rim diameter with two of the sidewall heights. It will result in a 22.4″ total tire diameter (or height).
