155/80R10 — what does it mean?
- 155 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
- 10 is a wheel diameter (or rim) in inches
How to convert 155 80R10 to inches?
First of all, we need to divide 155 mm (width) by 25.4 (mm to inch conversion), which will give us a width of 6.1″. Then, 80% of the 6.1″ will result in 4.9″ sidewall.
To get the total height or tire diameter, we need to sum the 10″ rim diameter with two of the sidewall heights. It will result in a 19.8″ total tire diameter (or height).
For your convenience, below is a table for 155/80R10 conversion to inches:
| Inches | Metric | |
