I got to store before it opened and a line already had formed. The staff got us all checked in quickly and smoothly. They anticipated my wait time to be 2 hours and I was done in less than one and half. They kept be updated in findings and progress of work. Staff was courteous and able to answer all my questions. This was first time we used this location, we will definitely go back

I was saved by this Big 0 and Micheal was incredible. I had driven into a pot hole that sliced my side wall. I was close by and googled tire shops close by. I knew I was only 2 blocks away and called ahead. They were closing in 5 minutes, Michael got my tire size and I said I needed the cheapest. I decided I need to replace 2 tires, as it is stupid to get 1 new tire. So I drove on my flat tire across federal and he waited for me. Him and his worker took care of me. Michael felt sorry for me, and gave me an unexpected price brake and included rotating my tires. I'm going thru rough times with a lot of medical bills, etc. I'm now loyal to this store and have told many people. Thank You so Much Michael!!!!

First I would like to thank the Tire Tech Crew I've been coming to this location for seven years you guys are awesome. In 20 minutes you guys got my Tires done. I was very impressed You guys work very hard at your job.The owner Mike Adams does not take care of you guys. He's Retired Now. he takes care of his Managers. but he doesn't take a look at the guys that work very hard in the back.Tires guy's should deserve a good Christmas bonus ( Mike Adams ) ! thanks jessica Jefferson from Castle Rock

I love Big O. In several years of doing business with them I have always felt that they have been honest with me. Other service centers I have been to wanted to do unnecessary work at a very high price and always told me it had to be done immediately.They see a woman coming and think we can take advantage of her. NOT Big O. They have told me work needed to be done but that it could wait, and on a few occasions they have checked out and solved my problem without charge. The only bad thing about them is not the service or treatment but the uncomfortable seating area for waiting. But to feel like your not being taken advantage of makes even that acceptable.

I showed up around 4:45 for a quick oil change. While it wasn't exactly quick, the service was great, facility was clean and convenient, and the experience was overall was good.

I had a nail in my tire and came right in on Wednesday morning. Very friendly let me drop my van off. Picked it up at lunch time. But after work that afternoon my tire was flat. Called and the gentleman apologized and said bring it right in. They worked to try to patch but it was unsuccessful. I got a new tire under warranty. These guys were wonderful. They were polite and apologetic the entire time. Even made sure low tire light went off! Will use again and recommend to friends!
