I am currently running Sumitomo HTR ZIII 255/35ZA19's on the rear (18's on front) that were new on the car when I bought it, and they have been great. I've never heard of the brand, but they have handled the abuse really well. They were sticky as hell on the dry, decent on the wet, just okay in the snow. I really beat the **** out of my Crossfire (frequently airborne/hard launches/rally-style off-road driving) , and I have gotten 23,000 miles out of them before I started losing traction. I will probably just buy the same tires, but still open to suggestions.
