115/70R14 — what does it mean?
- 115 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
- 14 is a wheel diameter (or rim) in inches
How to convert 115 70R14 to inches?
First of all, we need to divide 115 mm (width) by 25.4 (mm to inch conversion), which will give us a width of 4.5″. Then, 70% of the 4.5″ will result in 3.2″ sidewall.
To get the total height or tire diameter, we need to sum the 14″ rim diameter with two of the sidewall heights. It will result in a 20.4″ total tire diameter (or height).
For your convenience, below is a table for 115/70R14 conversion to inches:
|Overall diameter (height)||20.4″||518 mm|
|Tread width||4.5″||115 mm|
|Wheel diameter||14″||518 mm|
|Sidewall height||3.2″||81 mm|
|Revolutions||990 / ml||615 / km|
