Angel helped us right away to get on the road with our food trailer!! Clean facility and Great staff!!

Angel at the Thornton store as usual, very accommodating and extremely helpful I'm always well taken care of there. Thank you ​

Awesome staff! Angel and Tom communicated with me very well and got my truck up to date on its maintenance. Thank you!

Angel, Tom, and the entire Big O team at this location are fantastic. They're knowledgeable, professional, and genuinely trustworthy. I purchased a three-year alignment warranty, and they were upfront in letting me know that if I have future work done on my suspension, it could void the warranty. I really appreciate their honesty-so often, repair shops leave out important details or try to upsell unnecessary services. It's refreshing to work with technicians who are transparent, and I always feel confident that my vehicle is in good hands here. read more

Angel was wonderful from beginning to end. Getting new wheels for my vintage truck was not a routine affair. He had to search everywhere and managed to locate the last set available anywhere. He was patient and kind. I really do appreciate the extra work and care he put into helping me. My truck does too. And the young man who mounted the wheels was outstanding. It's a great place to go and deserves recognition for being the best tire shop I've been to. Plus, my compliments to the cleanliness and comfortable atmosphere created by Angle. He really does care and it shows. read more

It's my 2nd set of tires with these guys for my wife's ride. Last set of BigFoot held for 10 years with little driving she does. But save. We are planning to sell the car. But I wanna be sure she is still safe those few months. Thanks Robert for accommodating in short notice. read more

Came in on Christmas Eve, not thinking I'd be able to get my tire patched from a screw i had run over. Robert was very helpful to get my truck in, got it patched up and on the road pretty quick and painless. He went above and beyond to provide me with the quote I had requested for some new tires after the holidays and Gave me a few great options to consider. Looks like great value. Great customer service, thank you Robert read more

Angel was extremely welcoming and helpful with replacing my front tires. Turns out the current pair were a size too small and he showed me where to find my tire size on the door frame. We had to order my tires, but called me back as soon as he got them shipped in. Overall excellent service and will gladly come back while I am local to Thornton. read more

I passed by another Big O location closer to my home, to have my vehicle serviced here, based on the reviews I've read and my previous experience at the one closer to me. Angel hooked me up today, honoring my request for a pickup time before 3pm so I could make an afternoon appointment. He had initially indicated the work would take all day since I was having most of my suspension replaced front and rear, since my vehicle was approaching 120k miles. He said he'd do his best complete the repairs in time for me to make my appointment, which he absolutely did. When he called he said to head his way and he'd have my vehicle ready when I got there. I arrived just as the post-work test drive was wrapping up. Very happy first time customer at this location. read more

I came in to ask questions about my tires for a long trip. I really appreciated Roberts honesty and was extremely professional.

I had a wonderful experience at this location last week. What started out as just a flat tire, turned into a complete revamp of my 15 year old Nissan. Because of a death in the family, I haven't been taking care of my vehicle as I should. After putting my car up on the rack, Angel R, (__my!__ "ANGEL") explained that my car needed all oil, filters, and fluids flushed, an alignment, brakes, and tires rotated. I agreed because I knew I had neglected it. Angel, Richard, and Harry treated me well, even though it was all on me. THANKS GUYS!!!! read more

I went in for a transmission light,they made an honest attempt to fix, when they finished, the light was still on and the needed parts were only available at a Honda dealership. They restored mylar to running Co edition and because they weren't able to fix it without the parts, Angel, Service Mgr, knocked off all the associated costs,his words: 'why should you have t0 pay if we couldn't fix it!' Est service for all my auto repairs! 5 stars! It was a most rewarding opportunity to see such honesty in today's business world! Thank-you to Angel and Tom and all you Big O Techs! read more

They have been taken care of me for over 20 years. They have taken care of my tires as well as my vehicle. Great job!!!

This Big O was a dump. I avoided them for a long time. Finnaly went back to them, since they are near my home. Under new manager, this locationhas changed a lot. We have a RX-350. I got 4 new tires, realignments, and pads & Drums for rare breaks. Prices and service was quick. we also have a an outback that needed tire rotaion, Manager did a quick service. We purchsed these tires from them a while back. Free rotaion is part of Big O tuire prices. Now, we have no reservation about go back to this location. read more

Yes, I declined the offer to bring my car again because I have no interest in wasting any more of my time with this business. They've promised me twice now that the problem was resolved and twice now I've been disappointed to find it in fact was not fixed. Giving a 3rd chance and expecting different results is insane. As your limited warranty states, "If, after a reasonable number of attempts, the defect has not been fixed, the buyer may return his vehicle for a replacement of parts, if applicable, or a refund, in either case, subject to deduction of a reasonable charge for usage." A refund is the only resolution I will be accepting at the point. read more

Thanks AGAIN Big O Tires! read more

Firestone wanted to charge me fees they couldn't even explain and wanted to keep my car for a week. I called BigO, they ordered my tires, answered all my questions. I was prepared to leave my car there for the entire day. They called me less than 2 hours later. Tires and alignment done. Suggested work that my car needed but was not trying to push any sales on me. Friendly and hard working crew. read more

Wow! Had an appointment at 3 for 4 tires, they did not it get car in until 5:30. Manager indicated "this is happening too much" so ended up taken cost of one tire to make up for me waiting all this time. Fairly friendly bunch, just seem to not have any concept of time. This is really inexcusable performance, but at least I got some $ knocked off. read more
