What to write about

• A number that looks wrong — send the page address, the two sizes involved, and your source if you have one. Every figure here is computed from the size code, so a real error is a bug we want to fix.
• A size we are missing — if a common size is not in the chart or the dropdowns, ask and it goes on the list.
• Something broken — what you tapped, what you expected, what happened instead. Phone model helps.
• Anything else about the tools — requests, corrections, ideas.

What email cannot settle

Whether a tire will fit your vehicle. That depends on your wheel wells, wheel offset and suspension, and no inbox answer can measure them. The honest route is the five-minute check in will it rub? — and if you measure yours and the numbers surprise you, that is still worth an email.

About this site

TireCalcPro is a small independent tool site. Every number is computed from the standard tire-size formula — nothing is copied from other calculators — and the working is written up on the method page. There is no phone number on purpose: written answers keep the numbers checkable.
