T125/80R17 — what does it mean?
- T means "temporary"
- 125 stands for tread width in millimeters
- 80 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 T125 80R17 to inches?
First of all, we need to divide 125 mm (width) by 25.4 (mm to inch conversion), which will give us a width of 4.9″. Then, 80% of the 4.9″ will result in 3.9″ 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 24.8″ total tire diameter (or height).
For your convenience, below is a table for T125/80R17 conversion to inches:
|Overall diameter (height)||24.8″||630 mm|
|Tread width||4.9″||125 mm|
|Wheel diameter||17″||630 mm|
|Sidewall height||3.9″||100 mm|
|Revolutions||814 / ml||506 / km|
