175/65R13 — what does it mean?
- 175 stands for tread width in millimeters
- 65 is an aspect ration between the tread width and the sidewall in percents
- R means that the tire has a radial construction
- 13 is a wheel diameter (or rim) in inches
How to convert 175 65R13 to inches?
First of all, we need to divide 175 mm (width) by 25.4 (mm to inch conversion), which will give us a width of 6.9″. Then, 65% of the 6.9″ will result in 4.5″ sidewall.
To get the total height or tire diameter, we need to sum the 13″ rim diameter with two of the sidewall heights. It will result in a 22″ total tire diameter (or height).
