About TireSizesFinder

TireSizesFinder is an independent reference that calculates tire dimensions and size comparisons from the numbers printed on the sidewall.

Every page is generated from a list of common tire sizes and a small set of geometry formulas described on the methodology page. There are no product recommendations, rankings, affiliate links or advertising.

Start with the tire size calculator, or browse sizes by rim diameter from there.

TireSizesFinder is not affiliated with any vehicle manufacturer or tire manufacturer.
