195/45R13 — what does it mean?
- 195 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
- 13 is a wheel diameter (or rim) in inches
How to convert 195 45R13 to inches?
First of all, we need to divide 195 mm (width) by 25.4 (mm to inch conversion), which will give us a width of 7.7″. Then, 45% of the 7.7″ will result in 3.5″ sidewall.
To get the total height or tire diameter, we need to sum the 13″ rim diameter with two of the sidewall heights. It will result in a 20″ total tire diameter (or height).
For your convenience, below is a table for 195/45R13 conversion to inches:
|Overall diameter (height)||20″||508 mm|
|Tread width||7.7″||195 mm|
|Wheel diameter||13″||508 mm|
|Sidewall height||3.5″||88 mm|
|Revolutions||1009 / ml||627 / km|
