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.
Fontana sits in the middle of the region's freight movement, and the traffic a Fontana driver shares the road with is heavier than almost anywhere else in the Inland Empire. Stop-and-go behind loaded trucks on Sierra, Citrus and Cherry is the hardest kind of driving for brake pads and rotors, and the pavement those trucks leave behind is rough on tires and front-end components.
Distance is the other factor. Most Fontana customers reach us on the 10, and a daily commute that runs west in the morning and back east in the evening stacks up freeway miles fast. Heat, speed and pressure are what kill a tire on that kind of run, so an underinflated tire that feels fine around town is the one that fails on the freeway. Checking pressures before a week of freeway running is the cheapest thing a Fontana driver can do for a set of tires.
