Tyre sizes and bike comparisons

Two tools built on our sourced bike data: stock tyre sizes by model year, and any two bikes side by side. For engineering calculators, see the MotoWild Lab. They run in your browser: no account, no email, nothing stored.

Where the numbers come from

Bike specs and tyre sizes come from makers’ pages, launch coverage and spec databases, and each figure links to its source. Where a maker does not publish a number, the tools say so instead of guessing.
