In my quest to replace two of the stock tires on my car (one of which had a nice big nail in it), Discount Tire came through admirably.
Here's why:
1. I didn't even need to make an appointment! The Discount Tire website is supremely user friendly allowing you to not only locate the kind of tire you want but also schedule an appointment at the shop closest to you. I threw caution to the wind and walked in without my name on the list. They got me in right away.
2. I waited maybe 30 minutes. Granted, I went in on a Wednesday morning around 9am, but still. I was in and out before I could finish my coffee.
3. The tire selection is solid. I ended up choosing a slightly more expensive option because they were graded to last 65k miles. Both tires came out to about $240 which included installation, warranty, etc. There were still many cheaper selections too.
4. The repair warranty. Discount Tire will replace the covered tire even it is fails due to a defect or an unrepairable road hazard. Just be sure to use it within 3 years of purchase date. (http://www.discounttire.com/dtcs/infoCertificate.do)
I have always had a good experience coming into any Discount Tire store; this particular location was just closest to my house.
