ST205/75R14 — what does it mean?
- ST means "special trailer"
- 205 stands for tread width in millimeters
- 75 is an aspect ration between the tread width and the sidewall in percents
- R means that the tire has a radial construction
- 14 is a wheel diameter (or rim) in inches
How to convert ST205 75R14 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, 75% of the 8.1″ will result in 6.1″ 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 26.2″ total tire diameter (or height).
