Calculator inputs
Tire sizes and numeric values are calculated on your device. They are not sent to TireMath HQ servers, and the site has no accounts, uploads or vehicle profiles.
Browser storage
The site may remember the last valid tire sizes and your theme preference in local browser storage. That information stays in your browser and can be removed through your browser's website-data controls.
Analytics
TireMath HQ uses Vercel Web Analytics to understand aggregate page usage and site performance. The calculator values you enter are not included in analytics URLs or events.
Advertising
Advertising is not loaded unless it has been enabled for this domain. If enabled, Google AdSense may process device or browser information under Google's own privacy terms. TireMath HQ does not sell calculator inputs or user profiles.
External links
Links to other sites are governed by those sites' policies. This policy applies only to TireMath HQ.
