Gotta question. When is the right time to go up a level with tires? I am asking because I hear a lot about the Q4's , Perilli's, RS10's, Pilot Sport's etc being awesome track tires but is there really a difference with the commuter/canyon carver. Lets say you use your bike to go to work with a medium level twisties max speed = 80mph. The same speed for the straights during canyon carving but intermediate twisties. When is a good time to know when to move from a Q3 to the Q4?
