I had to get a flat fixed. Big O took care of it and I was blown away by the customer service. They should also be in the business of training other companies on how to take care of customers! Thank you very much Big O!

Very friendly service. Definitely fair prices on tires compared to the competitors. Car was ready and done when promised; actually they had it finished early! Highly recommend this Big O Tires location.

There was a puddle of oil in my driveway I did notify the store they're very helpful they offered to reimburse me if I'd buy any products to clean up and also to top off my oil if a lot was lost. They were very kind and professional about the situation a neighbor was able to tighten the bolt that apparently wasn't done right in the first place from your shop. I've been here before with my other vehicle and I probably will continue with this one until my son takes it to College thank you

I'm a busy mom whose tight on cash... I discovered a screw in my tire this morning. I went to big O tire after I got the kids from school in was told it was going to be a very long wait over an hour the gentleman offered to look at my tire to see if it was losing air. We discovered there was no air loss he was able to take the very tiny screw out there is no damage to my tire I did not have to wait he went above and beyond I will definitely give this place my business in the future and recommend it to anyone good people that genuinely care about others I did not feel like a number. I think other stores in town could learn something from this place finding people with heart is rare these days but they still exist give your business to big O tire!

I’ve been coming here for years, in that time I have always been treated to the very best in customer service. This has included not only tires but informing us of a recall that we hadn’t been notified of by the vehicle’s manufacturer. It doesn’t matter who waits on us, we are always treated with the utmost courtesy!

I come in so often (older cars) that we are all on a first named basis. The guys always take great care of me!
