Will somebody pinch this guy for me.

Owning a Cobra in a land with no speed limits on the highway! And then asking, Hey, what kind of tires do I put on this thing?"

OK, seriously. The bad news is this. The 15 inchers will have to go. But with almost any 17" you'd care to use, you can drive as fast as you want to, or dare to. Let no Benz, Beamer, or Porche kick sand in your face.

I'd be a little reuctant to recommend a brand, because anything US DOT approved for 55 MPH use alongside minivans and SUV's chugging along in the left hand lane, is garbage where triple digit highway speeds are common.

From my tire research, there are 2 things you need in a high perf tire for a Benz, Beamer, Porche, or Cobra. 1) AA traction rating on dry and wet roads. 2) "Z" speed rating or better. That's 149 MPH+

There is a Jap made tire that was track tested in Germany that stood toe to toe with the Michilen, Pirelli, Yokohama, Dunlop, Goodyear, BFG, and doesn't cost a fortune. Falken FK451. Have a set of 235/45's & 275/40's on mine. AA Traction, and Z speed rated.

There is also a thread here, "What tire is everybody using?" with numerous other suggestions/opinions.
