I give this place 10 stars. I've been coming here for many moon, (20 years). What a great bunch of people. A big thank you and I tip my hat to everyone. Off to Florida again. DRTYBRD is in the glove box should I ever need to reactivate. I recommend this place for anybody that needs repairs from people you can trust. Thanks again everyone and we'll see you again sometime.

Nice professional people, good service, good work. The only problem was the unbelievably high prices for services. They may have great prices for tires, but for other services, it's kind of outrageous.

I had taken my vehicle to this location several times in the past and had no choice multiple times recently. Thought I had a good honest relationship with Patrick. I trusted him so I trusted the shop. I went in for a suspension check was told it was my stabilizer links which I had replaced 1 yr ago ok fine Patrick got it under warranty but one of the employees there didn't like that he did that for me. I get my car back and as soon as i get in its making noise that is different and also worse so Blake text my car back into the bay leave the car running the whole time he takes off the tires and pretty sure he overgreased the links have to take the car back again because there's still noise and the handling feels worse have them replace the strut assembly I go to pick up my car and the windshield is broken they didn't call or notify me at all took it home and theres is stuff missing from my trunk popped the hood and saw that the grill and bumper weren't put back right and they broke my headlight housing along with a couple other things involving the reinstallation process. took it to another shop was told the links were the wrong size and it was hitting the knuckle. Got that replaced when they told me that it still making front and noise due to the strat assembly now I'm afraid to take it to any of the locations for them to honor this replacement. Blake gilliam should not be working on vehicles

After I refused a high priced service here back in July (I found someone to do it for thousands less the next day), someone here broke an engine shield and booby trapped my windshield wipers (crossed them up so they both broke off and scratched my windshield the next time I used them) and I just found out they cross threaded the bolts on my tires too as a sort of delayed booby trap that I just had to pay for. Legendary bad service.

Great crew at this Big O Tires location. Stopped in today needing my AC recharged. After stopping at Grease Monkey (who can’t no longer do this service) Patrick at Big O was able to get the job done in about 30 minutes. I’m recovering from surgery and needed to have this service done especially on a 100° day with no AC. Normally you need an appointment but he and his tech were able to accommodate me no questions asked. Just kind folks who want to do a good job at a fair price. Would highly recommend this crew who has good old fashioned customer service top of mind.

Once again Big O has saved the day. In each in every way. I went camping and it appears that some wires were chewed through. I thought I needed new components but they’re very awesome. Technician realize it was just a wiring issue and took care of it. 200 bucks out the door the guys at the counter Josh, Patrick and Brandon. A replacement battery for my key fob. I would highly recommend this place very personable.

Went in for tire rotation and have my brakes checked, they said about 45 minutes but we're done in about 30 minutes, said brakes were great and didn't try selling me new brake parts and service. I trust them to service my vehicle, and I've recommended them to people who might need vehicle maintenance or service, they are in my opinion very professional, not trying to gauge you for large amounts of money

The staff at this location is the absolute best! They genuinely care about treating people well, and not just making sales. They’re quick too! I dropped in with a low tire this afternoon and they had me fixed up in about 20 minutes. I’ll be back for sure!

Always willing to do Tire Maintenance at this location! While other locations may scoff at repairing flats or checking alignment, this Big O schedules and completed maintenance repairs without fail! I bought my tires at another Big O location and after getting turned away several times for repairs, I don’t even bother scheduling at the other location. Even through another location is closer to my house, I’ll make sure this Big O gets my new tire order business in the future. Thanks guys!

Had a great experience at Big O Tires works with Adam. Got an oil change and my tires rotated and the whole process was smooth and stress-free. Friendly staff, quick service, and I felt well taken care of. Highly recommend.

Big O (especially this location!!) is the only place I'll continue to take my Kia to get serviced. Everytime I've been in, Josh, Patrick and Brandon have all been nothing but cordial, honest, incredibly helpful and super knowledgeable in their trade! 5 stars all around!

I made an appointment to get some new tires and an oil change at 8am. I was there a little late but that had a spot waiting for me. I chose their Big O Big Foot A/T II tires for my Toyota Tundra. It was during their buy 3 get 1 free sale so I saved nearly $300. My first road trip was up to the mountains for a fishing trip with some friends. They all commented on what a smooth ride it was! I'm very satisfied with my new tires, the customer service and quality work my family and I have received at the Thornton Big O for the last 20+ years. Keep up the great work!

Big O Tires was so helpful with choosing the right tires for my truck. As a female I had no trouble at all and had one of the most honest experience with the team, they were helpful, prompt, efficient and friendly. The staff were funny and welcoming. The price was honestly the best pricing I had be quoted as well. Thank you so much, I am all ready for mud season! I’m happy with the tires they suggested and I’’ ready for my 4wd trip! Great job!

Exceptional Care from the Team! If any problems occur with our vehicles, this team is always there to help, including family members' cars. When the High Coolant Temperature warning appeared in my Bronco on a very cold Saturday, I called Patrick, and he gave me detailed instructions and asked me to bring it in. The team worked diligently and had the vehicle ready by the end of the business day. Patrick's personal involvement ensured a swift resolution. Unlike most dealerships and repair shops, this team is prompt and efficient. Their service consistently exceeds expectations. My family own various models of Ford, Jeep, and Dodge vehicles. I look forward to seeing you all again soon. The husband's car is now making noises. 🙄

Staff was more than accommodating. Very knowledgeable and professional. The prices are good and the bathroom was clean. Walking distance to many restaurants you can go have lunch while you wait. 10/10 love my new tires
