P215/45R16 — what does it mean?
- P means "passenger car"
- 215 stands for tread width in millimeters
- 45 is an aspect ration between the tread width and the sidewall in percents
- R means that the tire has a radial construction
- 16 is a wheel diameter (or rim) in inches
How to convert P215 45R16 to inches?
First of all, we need to divide 215 mm (width) by 25.4 (mm to inch conversion), which will give us a width of 8.5″. Then, 45% of the 8.5″ will result in 3.8″ 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 23.6″ total tire diameter (or height).
For your convenience, below is a table for P215/45R16 conversion to inches:
|Overall diameter (height)||23.6″||599 mm|
|Tread width||8.5″||215 mm|
|Wheel diameter||16″||599 mm|
|Sidewall height||3.8″||97 mm|
|Revolutions||856 / ml||532 / km|
