105/70R14 in inches

105/70R14 — what does it mean?

• 14 is a wheel diameter (or rim) in inches

How to convert 105 70R14 to inches?

First of all, we need to divide 105 mm (width) by 25.4 (mm to inch conversion), which will give us a width of 4.1″. Then, 70% of the 4.1″ will result in 2.9″ sidewall.

To get the total height or tire diameter, we need to sum the 14″ rim diameter with two of the sidewall heights. It will result in a 19.8″ total tire diameter (or height).
