Tire Shop & Auto Repair Serving Fontana, CA
Comtires is a family-owned tire and auto repair shop at the corner of Holt & Mountain in Ontario – a short drive west on the 10 from most of Fontana. ASE-certified mechanics, a nationwide 24-month / 24,000-mile warranty, and honest pricing since 2011. Walk-ins welcome.
The shop Fontana drivers trust for tires, wheels, and full auto repair
Fontana is a working town and a logistics hub. Daily commutes on the 10 and 210, fleet vans and work trucks running between warehouses, and weekend trips up to Lytle Creek and the San Bernardino mountains – vehicles in Fontana put in real hours. Tires lose tread fast in the heat, brakes get worked over and over in stop-and-go on Sierra Ave and Foothill Blvd, and suspensions take a beating on rougher industrial routes around Slover and Jurupa.
That’s the work we do. Comtires has been the family-owned shop at Holt & Mountain in Ontario since 2011 – a quick drive west on the 10 from most of Fontana. Plenty of our customers drive in from downtown Fontana, the Sierra Lakes area, North Fontana up near the 210, the Jurupa Hills neighborhoods, and the Auto Club Speedway side. We service everything from daily commuter sedans and family SUVs to fleet vans, work trucks, lifted off-roaders, and tuned imports.
