The top street tire makers are Bridgestone, Yokohama, Pirelli, and Michelin in that order. As of 2001, the Bridgestone S-03 is probably the top street tire in the world at this point. The Yokohama A032R and A038R are probably the top truly streetable soft (racing) compound tires. PZero Asimmetricos probably remain the top high speed tire, especially in Y ratings (for up to 186 MPH (300 km/h)).
