I've used Tirerack a few times. Always had good results. Saved some money. I used Eurosport in Norman for the install. They're tied into Tirerack's web page, so you can purchase the tires, and Tirerack will send them straight to the installer. Then Eurosport calls to setup an appointment. They even have a courtesy driver to get you to work/home and back while your vehicle is being worked on. Both Tirerack and Eurosport have been great to deal with.
