Affiliate Disclosure

We may earn a commission if you buy through links on this page.

This disclosure appears before the first commercial link on any page that has one, per FTC guidance (16 CFR Part 255). Today, this site has no active affiliate program and no commercial links anywhere -- this page exists so the policy is in place before any program is turned on.

How it will work once a program is active

• Any commercial or affiliate link will carry rel="sponsored nofollow".
• Clicking a commercial link never changes the price you pay.
• A possible commission never influences the calculator's results or the reference guides' content -- those are computed from the sizes you enter and from cited sources, not from which retailer pays the most.
• No advertisement or affiliate link is ever placed inside the calculator, next to its input fields, or next to its result buttons.

Programs this site may use

None of the following are active yet. This section will be updated, with real account status and dates, the day any of them goes live.

• Amazon Associates — not active
• Awin -- SimpleTire — not active
• Awin -- Priority Tire — not active

Brand and tire-size names mentioned anywhere on this site are used only to identify products (nominative fair use); mentioning a brand is not an endorsement and does not imply sponsorship.
