I am a car enthusiast, and take my tires really seriously. I was hesitant to go to a place with discount in the name, but, read some positive reviews on car forum sites. Don't let the name fool you, discount doesn't mean unskilled techs. The shop uses best of breed tools like Hunter road force balancers and Coats mounting machines.
The salesman was great. I was down to two choices and he gave me the educated advice I was looking for. He didn't try to push another product I wasn't interested in.
The price was as good as TireRack. What's great is you get lifetime rotation and balancing on the tires. That is a great value add, especially since tire manufacturer warranties require frequent rotation at an authorized tire dealer to stay in warranty (every 4-10k miles). They have a 30 day satisfaction guarantee (nice) and their own warranties.
The tech knew the right torque settings for my car - just using a torque wrench is rare for most lesser mechanics. Using one at the right setting is a good sign of skill.
The tech also gave me the full details on the road force balancing. Nicely done.
I'm one happy customer.
Two areas for improvement: the waiting area could use WiFi so you can work while you wait, and wish they offered nitrogen as an option (nitrogen is hard to find though-most distributors for tire shops went out of business in the downturn).
