Torqstorm 360 magnum
Although they are not for use in freezing temperatures, I really like the Nitto 555's in a 275/60-15's for street use. They have a 186 mph rating (fronts are rated to 149mph), are actually round and have a decent traction once they are in their preferred temperature operating range of not too hot and not too cold. I try and keep it under 150 mph these days, besides the speedo maxes out at 150 mph and the wind noise becomes deafening.
