295/65R18 — what does it mean?
- 295 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
- 18 is a wheel diameter (or rim) in inches
How to convert 295 65R18 to inches?
First of all, we need to divide 295 mm (width) by 25.4 (mm to inch conversion), which will give us a width of 11.6″. Then, 65% of the 11.6″ will result in 7.6″ sidewall.
To get the total height or tire diameter, we need to sum the 18″ rim diameter with two of the sidewall heights. It will result in a 33.2″ total tire diameter (or height).
For your convenience, below is a table for 295/65R18 conversion to inches:
|Overall diameter (height)||33.2″||843 mm|
|Tread width||11.6″||295 mm|
|Wheel diameter||18″||843 mm|
|Sidewall height||7.6″||192 mm|
|Revolutions||608 / ml||378 / km|
