The shop Upland drivers count on for tires, wheels, and full auto repair
Upland is one of those Inland Empire cities that sits between the foothills and the freeways, and that mix shows up in how vehicles wear. Daily commutes down the 210 or across the 10, school runs along Foothill Blvd, weekend drives up to Mt. Baldy and back - your tires lose tread faster than the sticker promised and your brakes feel the climb every time. Add in the older tree-lined neighborhoods south of Foothill and the newer hillside developments above 20th Street, and Upland customers bring us a wide mix of vehicles.
Comtires has been the family-owned shop just south of Upland on Holt Blvd in Ontario since 2011 - straight down Mountain Ave or Euclid Ave from most of town. We service daily commuters, family SUVs, work trucks, lifted off-roaders, fleet vans, and tuned imports. Customers come from across Upland - Downtown / Historic Upland, San Antonio Heights, the north side above the 210, and the south-of-Foothill neighborhoods that border Ontario.
Upland is an established town with established driving patterns. Euclid and Mountain run north to south through the whole city, the foothill neighborhoods above Foothill Blvd sit on a constant grade, and most trips end up on one of those two roads. A car driven mainly up and down a grade works its brakes and its cooling system harder than the mileage alone would suggest.
We also see a lot of second and third vehicles from Upland, the ones that stay in the garage and come out on weekends. Those are the vehicles where age matters more than mileage: belts and hoses dry out, brake fluid absorbs moisture, and tires age out of safe service while the tread still looks almost new. On a low-mileage car the date codes tell us more than the odometer.
