What Is the Metric Tyre Size to Imperial Calculator?

How Does the Calculator Work?
The metric tyre format looks like this: Width / Aspect Ratio R Rim. For example: 265/70R17.
Here’s what each number means:
- 265 = Width in millimeters
- 70 = Aspect ratio (sidewall height as % of width)
- R17 = Rim diameter in inches
The calculator uses a standard formula to turn that into actual inches for:
- Overall tire height
- Tread width
- Sidewall height
- Rim + sidewall total diameter
It’s the easiest metric tyre size to imperial calculator in inches you’ll find—just input and get your results instantly.
