Hi John
Personally, I wouldn't consider anything other than Goodyear Eagle GS-D3
I had a set on a Corvette and they were so superior to the OEM run-flats that they totally transformed the car. Traction, grip, turn-in, road noise and particularly water displacement (important for those TX deluges) was of the very highest order. My tires were monsters, but still very good value from Tire Rack - I think they were around $1300 for the set and like I said Vette tires are biiiig (345/45/19). Tire Rack delivered 'em to my local Goodyear Gemini and they put them on for 30 bucks. Best tires I ever rode on anyway!
Regards
Matt
