Calculate Tire Size
This form allows you to calculate the height of your tire sidewall based on the aspect ratio
and width of your tire.
Optionally, given the height of your wheel, this form will also calculate the overall height
of your tire. The information required is usually printed on the side of your tire in the form of something like
185/60R16. In this example, the width of the tire is 185mm, it has an
aspect ratio of 60% (that is, the sidewall height is 60% of the width of the
tire), and the wheel size is 16 inches.
