We have been going to this Big-O for years with pretty good service, but recently things have changed a bit. They have developed a habit of telling you that you need things that you do not need – this happened to us more than once with both of our vehicles, specifically shocks and struts. But a very recent visit has convinced us to no longer use this Big-O. During a recent tire change they neglected to tighten the lug nuts on one wheel and this caused $800 of damage to our vehicle. We noticed the vehicle making a new noise a... read more

Where do I begin? I had bearings seize last October and had the car towed to this Big O Tires for repair. They had the car 2 weeks and when I picked it up, I drove about 5 miles and right rear tire froze up on the highway at 55 miles per hour. Had it towed back the shop. Another week went by and they said it was fixed. I drove it until September of 2014 and the same bearings went out again. They told me they were nylon and changed them out as they were still under warranty. Again 2 month later the brakes started to sound lik... read more

Shame on you!!! I brought my car for an allignment. They told me before they could allign my car the inner and outer tie rod needed to be replaced. They said they were pretty bad and it needed to be done. They gave me a price estimate of over $400. I was hesitant because I really couldn't afford such a repair. Then he told me he could give it cheaper to me. He would only charge one and a half hour instead of two. So he came down to $363. This was still a lot of moeny what I had not expected. I told them that I like to wait a... read more

In a pinch – I get my oil here on occasion. They give me full diagnostics with price estimates, and treat me like I'm retarded, but they can change oil. I always take my car to a more specialized mechanic for actual repairs, but it's never been in worse condition after I've brought it there. Sometimes I'm definitely treated worse than others, one time they broke one of my truck keys, and in the middle of moving (didn't have time to leave it at the shop for repairs), to accentuate how badly I needed repairs, one mechanic aske... read more

Bad service, bad mechanics -- avoid! – 2nd bad experience in two weeks. My friend took his car in to get a wheel bearing replaced. They talked him into replacing struts. The car was fine, didn't need anything besides a new wheel bearing. They charged him $800 extra for crap he didn't need. I took my car in for an alignment. Screw ups: 1. They ignored the alignment settings I asked for. 2. They used the alignment settings from a different year of car than what I have. They also told me that a $250 part is required to setup ne... read more

Great service – I went to Big O to get new tires and an oil change, I happened to come to there buy 3 get 1 free sale which turned out to be a great deal and I spent $200 less then I was planning to. Everyone at the front was courteous and answered all of my questions that I had, they took the time to walk around the store with me and help me find what I needed. Dan at the front was very friendly and even cut me a deal for being a C.U. student. Highly recommended!!

Worst Shop Ever – I originally went to Big O after finding that they had the cheapest tire that fits my SUV in the area. Upon trying to buy the tire, they tried to upsell me to a SUV tire ranging in the price range of well over $175 each (over the $50 tire) claiming that my SUV couldn't run well on passenger car tires. After explaining to them that A.) I have passenger car tires on my car, and B.) I have worked in an auto body / repair shop owned by a family member since I was 5 until I went to college, and I know what I wan... read more

Great deal on brakes – The guys at Big O in Boulder are great, I have been going there for years. I went in for brakes, they gave me a great deal and were really friendly. They inspected my whole car for free and they gave me a ride to work. I can not believe how great the customer service was, it is hard to find that level of customer service now a days. I am going to take my car back next week for struts... THANKS GUYS...

Helped my C.U. student – I had to get tires for my daughter who is going to C.U. I live in California and did not know what to do. I called Big O tires in Boulder and talked to Dan. He worked out a great price over the phone and set up an appointment so she could get the work done the same afternoon. Not only was he really friendly, but he also gave me a discount because my daugher is a C.U. student. I really appreciated the great service and now I have a honest place to send my daughter too for all her car needs.
