AIWheelTech vs Wheel-Size.

Wheel-Size is a global wheel and tyre fitment database, launched in 2015, covering more than 250 makes and 60,000 vehicle modifications in 14 regional markets. It sells a REST API from a free sandbox to $450 a year for production use, a wheel configurator API and an official MCP server for AI assistants. AIWheelTech’s API works in any market, because fitment follows the model and chassis, not the country: it matches each vehicle against a live catalogue of wheels and tyres with trade prices and stock, finds UK cars straight from their number plate, adds DVSA MOT history, and scales from 1,000 free calls a month to Enterprise bulk delivery. A business that wants the longest vehicle list today, or the lowest price for fitment data alone, is better served by Wheel-Size. A retailer, wholesaler or platform that wants fitment tied to wheels and tyres it can sell is better served by AIWheelTech.
