I've ordered from Tirerack.com before and been happy. I love to read all the ratings and reviews on their site. Discount Tire Direct, though, is offering free shipping and a $50 rebate on a set of four tires (for some brands) that would save me a lot of money on the tires I'm looking at. Anybody have any negative comments about them? How is their rebate processing? I really don't want to get involved in a big rebate hassle. (These rebates are only good for about two more weeks.) The only thing negative I can see, not having ordered from them before, is that their selection is very poor compared to Tirerack. And of course, no user comments and surveys.
