185/75R14 — what does it mean?
- 185 stands for tread width in millimeters
- 75 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 185 75R14 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, 75% of the 7.3″ will result in 5.5″ 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 25″ total tire diameter (or height).
For your convenience, below is a table for 185/75R14 conversion to inches:
|Overall diameter (height)||25″||635 mm|
|Tread width||7.3″||185 mm|
|Wheel diameter||14″||635 mm|
|Sidewall height||5.5″||139 mm|
|Revolutions||808 / ml||502 / km|
