Thank you so much for your help today! My time belt broke and destroyed my engine. I was towed to the Big O store in Monement CO. They checked it out, told me my bad news, but they were very considerate, helpful, and let me keep my car there until I could figure out a more convenient time to get it out of there. They were just great! Thanks so much again! I appreciate it so much.

Rick was very professional and positive. He was very clear and accurate when explaining things, honest and not misleading or pushy. I appreciate that he greeted me at my vehicle and took care of my needs in a very timely manner. Rick was very friendly and made the experience fun and seem like I was only there for 10 minutes. I would be willing to make Big O my new tire shop. I've used Discount Tire for years and I don't think I'll go back again.

I originally went with a great price point tire that worked financially. I did not appreciate its performance. We ended up exchanging it with a great Michelin tire that exceeded my expectations at a very small additional charge! Staff was very understanding, zero drama and even checked my new alignment (I did with an oil change at an other no name facility) and did not charge for the correction. Great Place, Great People and my new home for oil changes and maintenance with people I can trust!

As usual, took really good care of me with new tires last week and an oil change/tire rotation the week before. Price was right and they have the sense of urgency to get me in and out that I need because I'm always on a tight schedule.

This is follow up and closure to my previous lengthy review. The matter/issue with the 4 tires that were mounted backwards has been satisfactorily resolved. Nick Boisvert provided a very fair solution to the situation and replaced the prorated tires. The exchange was fast and out of there just under an hour. Thank you, glad this is behind us.

Joe (new employee) ordered new tires to be delivered the next day. Unfortunately he ordered the wrong size resulting a delay of several hours before other tires could ordered and available- Generally your service is superb.

We came to Big O to replace 4 worn tires. Joe provided excellent customer service, explaining the various tire options to us, and letting us know of rebates available. He patiently answered all our questions which helped us determine which tires best suited our needs. We are very pleased with the tires we purchased and especially with the quality of service the team provided in getting the tires on quickly. Thank you, Big O!
