P225/75D16 — what does it mean?
- P means "passenger car"
- 225 stands for tread width in millimeters
- 75 is an aspect ration between the tread width and the sidewall in percents
- D means that the tire has a diagonal construction
- 16 is a wheel diameter (or rim) in inches
How to convert P225 75D16 to inches?
First of all, we need to divide 225 mm (width) by 25.4 (mm to inch conversion), which will give us a width of 8.9″. Then, 75% of the 8.9″ will result in 6.7″ sidewall.
To get the total height or tire diameter, we need to sum the 16″ rim diameter with two of the sidewall heights. It will result in a 29.4″ total tire diameter (or height).
For your convenience, below is a table for P225/75D16 conversion to inches:
|Overall diameter (height)||29.4″||747 mm|
|Tread width||8.9″||225 mm|
|Wheel diameter||16″||747 mm|
|Sidewall height||6.7″||169 mm|
|Revolutions||686 / ml||426 / km|
