T185/60D17 — what does it mean?
- T means "temporary"
- 185 stands for tread width in millimeters
- 60 is an aspect ration between the tread width and the sidewall in percents
- D means that the tire has a diagonal construction
- 17 is a wheel diameter (or rim) in inches
How to convert T185 60D17 to inches?
First of all, we need to divide 185 mm (width) by 25.4 (mm to inch conversion), which will give us a width of 7.3″. Then, 60% of the 7.3″ will result in 4.4″ 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 25.8″ total tire diameter (or height).
