What exactly happens when the tire to road contact patch moves beyond the edge of the tire? For example i used all my 150/60 tyre untill the edge, is it safe to downsized the size to 140?
I've spoken to the pirelli tire rep at our track days about this. He actually recommended the 140 for the rc and ninja 400. He said the 150s were a bit wide. Not bad for on the street, but you lose a little on the track.
