Our story
About Don Cortez Tire Services
Don Cortez Tire Services has been part of the neighborhood on Campus Ave for years, the kind of shop longtime customers still call by the same name their parents used. The shop has been upgraded over time, but the fast, personal service that built its reputation hasn't changed.
We check every tire before we recommend replacing it. More than one customer has come in expecting to pay for a patch and left owing nothing, because the nail never actually broke through. We would rather tell you the truth than make an unnecessary sale.
When you need tires fast, whether it's a full set or a single flat, we get you back on the road without the wait. Doors open early most days, so a flat tire doesn't have to wreck your whole morning.
- Honest inspections, no upsell

What customers say
“Love that they are open early. He got me in & out, which I'll always appreciate being a busy girl. Super helpful as well, making sure all my tires were good for my drive this weekend.”
“They were really nice and honest. They made sure all my tires were taken care of. They were so kind to still check all my tires had enough air and, regardless of them taking the tire off to check it, they did not charge me. I'm glad they were honest about it and did not try to take advantage of my confusion on thinking the tire actually needed to be patched.”
“This place is amazing! I had an awesome experience. The guys working there were polite, professional and so fast! They quickly changed my tires and got me on my way! They were extremely reasonably priced! I will be going there for all my future tire needs!”
