Tire size chart
[Tire diameter & Rim diameter]

I made a tire sizes chart [Tire diameter & Rim diameter]. If you want to change your tire width, rim diameter, aspect ratio, etc. without changing the tire diameter, please refer to the chart.

In the table, the columns have rim diameters, from 12 to 20 inches. However, 12 inches or less are listed in one column. Also, 21 inches or more are listed in one column. The rows have tire diameters from 480mm to 900mm in 10mm increments.
The values in parentheses in the table are tire tire diameters calculated by the following formula.

If you click on the value of tire width, aspect ratio, rim diameter, or tire diameter in the table, you search for tires and/or wheels of the size on the Amazon shopping site.
For example, if you click the tire width value "145" in "145/70R12(508)", you can search for 145/70R12 "snow tires". Similarly, if you click on aspect ratio "70", rim diameter "12", tire diameter "508", you can search for "snow tire & Wheel packages", "summer tire", "summer tire & Wheel packages".

I think it's convenient to find out what brands of tires are available and how much they cost.
