How is tyre profile calculated?

Tire width (mm) Aspect ratio (%) Wheel size (in.) The number 70 is the aspect ratio, sometimes called the profile. This is the ratio of the sidewall height to the width. The sidewall height can be calculated by multiplying the ratio (70 or 0.70) by the width (225): 225 millimeters x 0.70 = 157.5 millimeters.
