215/60R15 — what does it mean?
- 215 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
- 15 is a wheel diameter (or rim) in inches
How to convert 215 60R15 to inches?
First of all, we need to divide 215 mm (width) by 25.4 (mm to inch conversion), which will give us a width of 8.5″. Then, 60% of the 8.5″ will result in 5.1″ sidewall.
To get the total height or tire diameter, we need to sum the 15″ rim diameter with two of the sidewall heights. It will result in a 25.2″ total tire diameter (or height).
For your convenience, below is a table for 215/60R15 conversion to inches:
|Overall diameter (height)||25.2″||640 mm|
|Tread width||8.5″||215 mm|
|Wheel diameter||15″||640 mm|
|Sidewall height||5.1″||129 mm|
|Revolutions||801 / ml||498 / km|
