I've got 3300 miles on my 2010 Z with the Dunlop 210 tires. I'm one good ride away from needing to change them out. I've been running Dunlop Q2s on my CBR and plan to use them on the Z. My question is to those who have gone from a 190/50 rear to a 190/55. I understand the reason , more sidewall when turned in along with quicker turn ins. Given that the bike turns in quicker with the 55 does that mean it is sluggish coming out of the corners with the taller profile? Also how does the taller profile wear when putting straight line highway miles on the bike, takes about an hour of highway riding for me in NJ to get to the good twisties. Do they wear with a big flatspot at the tallest part of the profile? Thanks for the feedback from those who have made the switch.
