215/35R17 — what does it mean?

How to convert 215 35R17 to inches?

First of all, we need to divide 215 mm (width) by 25.4 (mm to inch conversion), which will give us a width of 8.5″. Then, 35% of the 8.5″ will result in 3″ sidewall.

To get the total height or tire diameter, we need to sum the 17″ rim diameter with two of the sidewall heights. It will result in a 23″ total tire diameter (or height).
