335/55R20 — what does it mean?
- 335 stands for tread width in millimeters
- 55 is an aspect ration between the tread width and the sidewall in percents
- R means that the tire has a radial construction
- 20 is a wheel diameter (or rim) in inches
How to convert 335 55R20 to inches?
First of all, we need to divide 335 mm (width) by 25.4 (mm to inch conversion), which will give us a width of 13.2″. Then, 55% of the 13.2″ will result in 7.2″ sidewall.
To get the total height or tire diameter, we need to sum the 20″ rim diameter with two of the sidewall heights. It will result in a 34.4″ total tire diameter (or height).
For your convenience, below is a table for 335/55R20 conversion to inches:
|Overall diameter (height)||34.4″||874 mm|
|Tread width||13.2″||335 mm|
|Wheel diameter||20″||874 mm|
|Sidewall height||7.2″||184 mm|
|Revolutions||586 / ml||364 / km|
