Overall the experience was great but when getting back into my car the stuff that was in my glove compartment was all over my front seat. I understand the need to get into the glove compartment but that was my last impression of the store as I left.

Unlike your counterpart on 840 West Hampden, the service we received was beyond expectation. They are honest, reasonable and our mechanic provided fast and quality work. I always thought costs for repairs were the same at all Big O Tires, but not so unfortunately. I will continue to have my vehicle serviced only at the South Federal location in the future. Thank you for the great and honest work Del.

I was blown away by the incredible customer service they offered! Tim was wonderful, helped me get the best option for me, and made me feel like a guest while they worked on my car. As a result, this will now be my go-to destination for auto work!

Good customer satisfaction

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 love this store and the staff. They are pleasant and friendly and go out of their way to give great service. I have experienced and witnessed the crew taking time to figure out reasonable solutions to avoid high costs for customers. Kudos!

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!!!!

I would have rated customer service a "5", but they forgot to tell me that my car was ready

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
