195/40R16 — what does it mean?
- 195 stands for tread width in millimeters
- 40 is an aspect ration between the tread width and the sidewall in percents
- R means that the tire has a radial construction
- 16 is a wheel diameter (or rim) in inches
How to convert 195 40R16 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, 40% of the 7.7″ will result in 3.1″ sidewall.
To get the total height or tire diameter, we need to sum the 16″ rim diameter with two of the sidewall heights. It will result in a 22.2″ total tire diameter (or height).
For your convenience, below is a table for 195/40R16 conversion to inches:
| Inches | Metric | |
