50% off on Federal 595RS-PRO
 

Phil's Tire Service are selling in stock Federal 595RS-PRO at 50% when purchased in pairs (so 2 or 4 tires will give you 50% off on the entire order).
Still available in 215, 225, 235 and 255. Sadly 245/40R17 is sold out.

Not a lot of feedback on these (here and across the web), but they appear to be on par with the GT Radial SX2 - cheap, can take track heat, wear well on track, not a ton of grip. For $80 to $90 a tire these should be great for HPDE.
