165/45R17 — what does it mean?
- 165 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
- 17 is a wheel diameter (or rim) in inches
How to convert 165 45R17 to inches?
First of all, we need to divide 165 mm (width) by 25.4 (mm to inch conversion), which will give us a width of 6.5″. Then, 45% of the 6.5″ will result in 2.9″ 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 22.8″ total tire diameter (or height).
For your convenience, below is a table for 165/45R17 conversion to inches:
|Overall diameter (height)||22.8″||579 mm|
|Tread width||6.5″||165 mm|
|Wheel diameter||17″||579 mm|
|Sidewall height||2.9″||74 mm|
|Revolutions||885 / ml||550 / km|
