tyre profile

[Shifu]

i edge my power 190/50's, but i kill my boots on the road already, wouldnt want to get over any further

revhead, id still consider that old one a good tyre, has more tread than im used to :P

Like you I use the 190/50 edge to edge on the road. 190/55 gives you an extra 4 deg of lean angle and on the road I am still 1/4 inch from the edge. On the track however it is a different story and all the way to the edge on 190/55 presents no challenge while on the 50 profile it easy to run out of the tyre. So in my opinion if you ride exclysively on the street 50 is the go unless you know the road is clean and willing to take the risk.
