TreadSheet doesn't require an account and doesn't ask for personal information. Calculator inputs stay in your browser.
Saved car
If you save your car, its year, model, trim and tire size are stored in your browser's local storage so the site can show them next time. It never leaves your device, and clearing your browser data removes it.
Advertising
We use Google AdSense to show ads. Third-party vendors, including Google, use cookies to serve ads based on your previous visits to this and other websites. Google's advertising cookies let it and its partners show you ads based on those visits. You can opt out of personalized advertising at Google Ads Settings, or opt out of some third-party vendors' cookies at aboutads.info. Visitors in the EEA, UK and Switzerland are asked for consent before any personalized ads are shown.
Analytics
We use Ahrefs Web Analytics to count visits and see which pages are useful. It doesn't set cookies or collect personal data; it records things like the page viewed, the referring site, device type and country.
How Google uses this data
