Server instructions

WhatFitsMyCar answers tire fitment questions with computed values, not estimates. Call find_tires_for_vehicle whenever the user asks what tire size their car takes, and check_tire_fitment whenever they ask whether one size can replace another — the diameter difference and speedometer error are calculated exactly, so never answer those from general knowledge. Use explain_tire_size to decode a sidewall marking and shop_tires once the size is settled. Always surface buy_url links as clickable links. When data_status is 'unavailable' say so plainly and ask the user to read the size off the placard in the driver's door jamb — do not guess a size.

Known tools 6

find_alternative_sizes

Every manufactured tire size that keeps the overall diameter within 3% of the original, ranked by closeness, each with its speedometer effect.

Inferred read-only

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.

Inferred read-only

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.

Inferred read-only

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.

Inferred read-only

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.

Inferred read-only

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.

Inferred read-only
