Once again, the gentlemen at Big O did not disappoint! Sean bent over backwards to help me out with the best deal on some much-needed repairs as well as finding me the EXACT tires I wanted for my big sissie wheels for me! It is always such a pleasure to work with everyone at this Longmont store!

After years of great experiences with other Big-O locations, I insisted on taking a family member's vehicle to the Longmont location when new tires were needed. As always, the treatment, pre & post sale, has been excellent. Obviously, any business prefers to sell high-end products. But, understanding my need to balance safety, quality and cost, there were no high-pressure sales tactics. The work was done well & I was back on the road quickly. When a fix was needed, months later, it was "service with a smile", and I was back out the door in under 30 minutes.

Great Service and knowledegeable advice: Just spent $2,600 on tires, brakes and shocks for all 4 corners on 2005 Ford Excursion 6.0L. They had what I wanted. They did not try to sell me what I did not require. "Turn-around" time was great.Staff and technicians were talented and knowledgeable. Prices fair and reasonable. I will be back.

Excellent all around tire service place: All of the front desk men were so helpful and even stayed late past closing time to get my service done. These guys are Bill,Sean,Andy,Cory and Mike.

Got a flat and took my car to Big-O, I needed to get some new tires in a hurry and get the mounted in a hurry as well. They were able to get my tires in by the next morning and mounted them that morning in 45 mins.. That has never happened for me in any of the other tire stores I've been to!! Price was good for the tires and additional work as well.
Bill was honest and fair about what I needed and charged me accordingly. He wasn't out to take advantage of a first comer or a woman. Thank you Bill....need more people like you. Even though the Internet was down, Andy managed to get me though without a hitch. Thank you Big-O.......I will be back, you can count on it!! Satisfied Customer.

I have used this store since moving to Firestone and I have been approached quickly and they have always performed well. They do not try to sell you something that you don't need.
