255/60R17 — what does it mean?
- 255 stands for tread width in millimeters
- 60 is an aspect ration between the tread width and the sidewall in percents
- R means that the tire has a radial construction
- 17 is a wheel diameter (or rim) in inches
How to convert 255 60R17 to inches?
First of all, we need to divide 255 mm (width) by 25.4 (mm to inch conversion), which will give us a width of 10″. Then, 60% of the 10″ will result in 6″ 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 29″ total tire diameter (or height).
For your convenience, below is a table for 255/60R17 conversion to inches:
|Overall diameter (height)||29″||737 mm|
|Tread width||10″||255 mm|
|Wheel diameter||17″||737 mm|
|Sidewall height||6″||153 mm|
|Revolutions||695 / ml||432 / km|
