205/70R13 — what does it mean?
- 205 stands for tread width in millimeters
- 70 is an aspect ration between the tread width and the sidewall in percents
- R means that the tire has a radial construction
- 13 is a wheel diameter (or rim) in inches
How to convert 205 70R13 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, 70% of the 8.1″ will result in 5.7″ sidewall.
To get the total height or tire diameter, we need to sum the 13″ rim diameter with two of the sidewall heights. It will result in a 24.4″ total tire diameter (or height).
For your convenience, below is a table for 205/70R13 conversion to inches:
|Overall diameter (height)||24.4″||620 mm|
|Tread width||8.1″||205 mm|
|Wheel diameter||13″||620 mm|
|Sidewall height||5.7″||144 mm|
|Revolutions||827 / ml||514 / km|
