Tire Shop & Auto Repair Serving Rancho Cucamonga, CA
Comtires is a family-owned tire and auto repair shop at the corner of Holt & Mountain in Ontario — a short drive south from most of Rancho Cucamonga. ASE-certified mechanics, a nationwide 24-month / 24,000-mile warranty, and honest pricing since 2011. Walk-ins welcome.
The shop Rancho Cucamonga drivers trust for tires, wheels, and full auto repair
Rancho Cucamonga sits up against the foothills, and that geography is hard on vehicles. Suspension takes a beating on the climb up to Alta Loma, tires age fast in the dry heat off Foothill Blvd, and brakes get worn down on the long downhill drives back into the valley. Add in daily commutes on the 210 and 15, the school runs across Etiwanda and Day Creek, and weekend trips up to the mountains — and the wear shows up earlier than the tire sticker promised.
That’s the work we do. Comtires has been the family-owned shop at Holt & Mountain in Ontario since 2011, and a meaningful share of our customers drive down from Rancho — Victoria Gardens, Alta Loma, Etiwanda, the older Cucamonga neighborhoods, and the newer developments out toward Day Creek. We service everything from daily commuter sedans and family SUVs to lifted trucks, fleet vans, and tuned imports.

What Local Customers Say
Frequently Asked Questions
Do you have a tire shop in Rancho Cucamonga?
Our physical shop is in Ontario at the corner of Holt Blvd & Mountain Ave — a short drive south from most of Rancho via the 15 or surface streets. We’ve been serving Rancho Cucamonga customers since 2011.
Is it worth the drive from Rancho Cucamonga?
Most of our Rancho customers tell us yes. We’re a family-owned, ASE-certified shop with a nationwide warranty, transparent pricing, and a long-standing reputation in the Inland Empire. The short drive south usually saves customers money compared to dealerships and chain shops up the hill.
Do you offer shuttle service for Rancho customers?
We offer complimentary shuttle service for customers dropping off vehicles. Coverage and availability depend on the distance and the day’s shop schedule — ask your service advisor at drop-off and they’ll let you know what’s possible.
How long does a tire installation or oil change take?
A standard 4-tire install with balance and TPMS reset typically runs 45–60 minutes. Most oil changes are done in 30–45 minutes. Alignments and larger jobs take longer — we give you a clear time estimate at check-in.
Do you finance tires and repairs?
Yes. We offer Goodyear Credit, Snap, Progressive Leasing, Koalafi, and AutoPass financing. Several options take a few minutes to apply for in the shop and don’t require traditional credit.
