285/55R16 — what does it mean?
- 285 stands for tread width in millimeters
- 55 is an aspect ration between the tread width and the sidewall in percents
- R means that the tire has a radial construction
- 16 is a wheel diameter (or rim) in inches
How to convert 285 55R16 to inches?
First of all, we need to divide 285 mm (width) by 25.4 (mm to inch conversion), which will give us a width of 11.2″. Then, 55% of the 11.2″ will result in 6.2″ 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 28.4″ total tire diameter (or height).
