check_tire_fitment — Compares a candidate tire size against the original: exact overall-diameter difference in percent and mm, the resulting speedometer error, and whether the load index and speed rating still qualify.
find_tires_for_vehicle — Factory tire and wheel sizes for a specific year, make and model, including staggered front/rear setups and every optional wheel size, with links to buy that exact size.
decode_vin — Decodes a 17-character VIN into the exact vehicle (make, model, year, trim, body, drive type, TPMS type) using the official NHTSA database, then returns the tire sizes for it.
shop_tires — Available tires in a given size with per-tire and per-set prices where merchant data is loaded, plus links that open each retailer's results for that exact size.
explain_tire_size — Decodes a tire sidewall marking into its parts: section width, sidewall height in mm, wheel diameter, overall diameter, load index in kg, speed rating in km/h, and the rim widths it may be mounted on.
