I've been to this location twice in the last year. The first time I visited they told me I still had a few thousand miles left before I needed to buy new tires so they ended up rotating them for free.
My most recent visit was to replace all four of my tires. I did my research on the internet prior to visiting and they definitely had competitive pricing. I'll buy my tires here anytime over buying online because the installation is free and the staff always treats me with respect. They're friendly, they work efficiently and they always provide excellent customer service.
I also like buying my tires at Discount Tire because they have great warranties. I can't count how many times they've fixed my tires for free (usually due to nail damage).
One final note - I like that I can walk to Nordstrom Rack and World Market while my car is being worked on. :) The store always sends me a text when my car is ready to be picked up - that's convenience!
