P405/25R24 — what does it mean?
- P means "passenger car"
- 405 stands for tread width in millimeters
- 25 is an aspect ration between the tread width and the sidewall in percents
- R means that the tire has a radial construction
- 24 is a wheel diameter (or rim) in inches
How to convert P405 25R24 to inches?
First of all, we need to divide 405 mm (width) by 25.4 (mm to inch conversion), which will give us a width of 15.9″. Then, 25% of the 15.9″ will result in 4″ sidewall.
To get the total height or tire diameter, we need to sum the 24″ rim diameter with two of the sidewall heights. It will result in a 32″ total tire diameter (or height).
For your convenience, below is a table for P405/25R24 conversion to inches:
|Overall diameter (height)||32″||813 mm|
|Tread width||15.9″||405 mm|
|Wheel diameter||24″||813 mm|
|Sidewall height||4″||101 mm|
|Revolutions||631 / ml||392 / km|
