225/65R17 isn't a mystery — it's a size, a speed rating, a treadwear number and a birth date, printed on rubber. TireScout reads it with you, prices it live, and does the per-mile division a shop quote never shows.
Free decode
The search above prices your size on live marketplaces. The box below decodes the paper: a shop quote, a tire listing, or the numbers off the sidewall.
Live listings — published marketplace APIs
Why this exists
An 80,000-mile tire at $178 costs less per mile than a 65,000-mile tire at $118 — before the install-price games start. The federal UTQG treadwear grade and the manufacturer's mileage warranty are printed public numbers; the division is the part nobody does at the counter.
How it works
It's on the sidewall: 225/65R17. The live search prices it across marketplaces with links out.
Install, disposal, TPMS, road-hazard — every line sorted into the tire's price and the shop's add-ons.
On a paid plan: the per-mile comparison grid, the ask-the-shop list, and the DOT-date check for used tires.
