We use Discount Tire for track and street rubber!
I made a good contact at the new Discount Tire in Cedar Hill off Hwy 67 and Beltline Rd. They are 5 mintues from my shop. The managers name is Bruce and he is going to stock one set of 555's and pair of DR's at his store. His prices are 10-20 bucks cheaper per tire than any other store. Nitto 555's 295/45/18's and DR's305.45.18's for the L. The prices I have worked out for TALON members is $195 for the Nitto 555's or Toyo Proxes, $230 for Nitto Drag Radials. That includes mounting and lifetime balance. I reccomend you to use them for all of your tire needs. Bruce works very hard to give us the lowest price you will find on anything you need.
