Affiliate Disclosure
Last updated: 10 November 2026.
TyreCalc is free to use, and it is supported in part by affiliate marketing. Some links on this site — for example links to tyre retailers, wheel retailers, auto parts stores and Amazon — are affiliate links. If you click one and buy something, we may earn a commission, at no extra cost to you.
What this does not change
Affiliate links never change a calculation, a comparison, a chart or a recommendation. A tyre size calculator gives the same answer whether or not you click a retailer link, and we do not rank or recommend products because they pay a commission. Where a guide mentions a retailer, it is because the retailer is a useful place to buy the thing being discussed — not because of the commission.
Advertising
The site also shows display advertising. Advertisers do not influence our content, and our content does not endorse any advertiser.
