Tirefolio Find my fitment

Methodology

Every page on this site relies on three data layers. This page explains where each comes from, how we verify it, and how often it refreshes.

Layer 1 — Fitment data

Tire and wheel fitment (size, rim diameter, offset, PCD, load index, speed rating) is sourced from manufacturer placards and OEM fitment registries. Our primary scrape source is wheel-size.com, which aggregates published manufacturer specs. We cross-check OEM fitments against the actual door-jamb placards listed by manufacturers and against published owner manuals. Fitment data refreshes monthly via a delta-sync against the source sitemap.

Layer 2 — Tire specs (UTQG, warranty, dimensions)

UTQG treadwear, traction, and temperature ratings come from the NHTSA UTQG database, which is the legally authoritative US source. Warranty mileage comes directly from manufacturer-published documentation. dB noise figures, where available, come from the EU tire-label database. We do not publish UTQG numbers from blog posts or retailer listings.

Layer 3 — Merchant prices

Prices come from the official affiliate-program data feeds we are enrolled in: SimpleTire (Awin), Priority Tire (Awin / ShareASale), TireBuyer (ShareASale), and TyresAddict (direct API). Each feed pulls nightly. We display the captured timestamp on every price block — if you see a price quoted, it was that price at the merchant within the last 24 hours. We do not surcharge or markup the prices we display; clicking through takes you to the merchant's posted price.
