Discount Tire is always incredibly busy - which is very frustrating.
However, they do take appointments (a little known fact) and they almost always have one open that day.
If you have an appointment, expect to wait less than one hour for a full new set of tires.
The service has always been good and the technicians polite - and the building itself is in a central location. I would recommend Discount Tire to anyone - but caution that an appointment is absolutely necessary.
Another plus is that Discount Tire will repair any tires they sell free of charge, and the warranty they offer on their tires is good at any of their stores nationwide.
