P245/65R17 — what does it mean?
- P means "passenger car"
- 245 stands for tread width in millimeters
- 65 is an aspect ration between the tread width and the sidewall in percents
- R means that the tire has a radial construction
- 17 is a wheel diameter (or rim) in inches
How to convert P245 65R17 to inches?
First of all, we need to divide 245 mm (width) by 25.4 (mm to inch conversion), which will give us a width of 9.6″. Then, 65% of the 9.6″ will result in 6.3″ sidewall.
To get the total height or tire diameter, we need to sum the 17″ rim diameter with two of the sidewall heights. It will result in a 29.6″ total tire diameter (or height).
For your convenience, below is a table for P245/65R17 conversion to inches:
|Overall diameter (height)||29.6″||752 mm|
|Tread width||9.6″||245 mm|
|Wheel diameter||17″||752 mm|
|Sidewall height||6.3″||159 mm|
|Revolutions||682 / ml||424 / km|
