Terms of Service
Last updated: 2026-10-27
These terms apply to your use of Tire Size Comparison at https://tire-size-comparison.pages.dev (the "Site"), operated by an independent developer ("we", "us"). By using the Site, you agree to these terms. If you don't agree, please don't use the Site.
1. What the Site is
The Site is a free, browser-based calculator that compares tire sizes: it works out overall diameter, width, sidewall height, revolutions per mile and speedometer difference from the size codes you type. You don't need an account. The Site is not directed to children under 13.
2. Information only; not professional advice
All results are calculated from the size codes with standard formulas and are provided for general information. They do not tell you whether a tire will fit, rub, be safe or be legal on your vehicle. Before you buy or fit tires, check your vehicle's tire placard or owner's manual and ask a qualified tire professional. See our Disclaimer.
3. Your input
The sizes you type stay in your browser (see our Privacy Policy). We don't receive or store them.
4. Acceptable use
You agree not to:
- interfere with or disrupt the Site, or try to gain unauthorized access to it;
- use automated means to put an unreasonable load on the Site;
- copy the Site's name, design, or content in a way that suggests you are us or are working with us;
- use the Site for anything unlawful.
5. Free to use
The Site is free to use and has no paid features. If we ever add paid features, we will publish their price, billing terms and a refund policy before you can pay.
6. Intellectual property
The Site's design, code and text belong to us or our licensors. Tire, vehicle and retailer names mentioned on the Site belong to their owners, and mentioning them doesn't mean they endorse us or work with us.
7. Changes to the Site
We may change, suspend, or stop any part of the Site at any time, with or without notice.
8. No warranty
The Site is provided "as is" and "as available", without warranties of any kind, to the extent allowed by law. We don't promise that results are error-free or suitable for your vehicle.
9. Limitation of liability
To the extent allowed by law, we are not liable for any loss or damage arising from your use of the Site or from relying on its results, including any decision to buy, fit or drive on a particular tire size.
10. Changes to these terms
We may update these terms; the "Last updated" date shows the latest version, and continued use means you accept the update. Nothing in these terms limits rights you have under mandatory consumer law where you live.
