I worked for Discount Tire for number and have been somewhat brand loyal due to that fact. I need an alignment fast, and Big O could accommodate. Gizmo was a great help, knowledgeable friendly willing to take time and definitely help me out of the situation I was in. Definitely left happy and will come back again. Thank you

I was driving to meet my sister for lunch when the tire light came on. I suspected a slow leak. Took the car to the nearest tire store which happened to be the Big O location on 120th and Lamar in Broomfield. Customer Service was ready to fix it immediately, but I said I would be back after lunch. When I returned, my car was waiting for me and to my surprise there was no charge. Broomfield: give this store your business!

I love these guys! They are honest, efficient and super nice to the customers. They have my business forever! I have referred several other folks to them as well.

I came in for a repair of a tire with nail damage. I had spoken with Gizmo on the phone and he promptly evaluated the tire, which had to be replaced. They didn’t have the tire at the store, so Gizmo went to pick me it up at their warehouse that same morning, and they had my car ready in just 3 hours. I cannot thank him enough for helping me out.

Professional and reasonably priced.

“Gizmo” was excellent. He helped me from the get go and was able to fix my tire even though it had a bad gash. Customer for life.

I had a noise in my car for about three weeks and I took it in to get checked. The noise was not being caused by what I predicted and the issue was more serious than anticipated. Luckily, my car received all the time and attention it needed to fix the noise. So far, my car sounds good and I know if something else goes wrong, I can go back to your shop to get it fixed. Thanks for your help!

Hi Lee, It was great seeing you yesterday.....and the Hellcat as well. I didn't know you are Kari's sister, I knew her for years at Oberon and A-West. I guess your store will be my tire supplier from now on.

Great, friendly service.

Gizmo, Justin, and the rest of the staff went above and beyond expectations. I had a little bit of bad luck and they really helped me out by staying after closing time, going to pick up parts, and unfortunately they still had to work on my car the next day. The next day, they finished fixing my car at their promised time. They were very friendly and understanding the entire time!
