Every page on AutoTyreSize starts with one question that real owners search for, such as the tyre size of a particular car or the right pressure for a scooter carrying two people. Here is how a page gets from that question to your screen.
1. Collect the figures
We look for the maker’s own numbers first: brochure spec tables, owner’s manuals and the tyre placard inside the driver door. Where the maker does not publish a figure, we look for two independent sources that agree. Figures that we cannot confirm are left out or clearly marked, never guessed.
2. Build the fitment card
Each vehicle has one record that holds its checked tyre sizes, pressures and part sizes. Every page about that vehicle reads from the same record, so the size on the pressure page always matches the size on the tyre page.
3. Draft and review
We use AI writing tools to help with first drafts and with checking that every page follows our style rules. A person then checks each figure against the sources, rewrites what reads poorly and adds the practical detail that comes from working in a tyre bay. No page is published without that review.
4. Photos
The photos on this site are illustrations made for us. They show generic, unbranded vehicles and parts, not the exact model a page is about.
5. Keep it current
Makers change wheels and tyres between versions. When a reader reports a change or we spot one, we update the record and every page that uses it. See our editorial policy for how corrections work.
