I've cooked the Rosso II rear in 3000 miles and put on a Rosso III. The tyre was dried out via repeated heat cycles rather than worn tread. There was a susbstantial loss of grip and feel. It was probably a result of how I ride and the pressures I prefer. I prefer a stiffer tyre carcass with lower pressures, (probably should go back to Dunlops.
).
Imo the Rosso III feels like a developmental improvement again with more edge grip, feel and quicker warm up. I think it has a stiffer side wall and carcass which feels better to me. I guess technology marches on.
That pretty much matches my experience. Looking back at my maintenance log, I burnt up my first II in 2000mi, the second at 2600mi. My III has been on for 2100mi, and it's still looking pretty good. I put a III front on, finally, after 6600mi, just this past November... I have but 200mi on it, so far. The III is definitely a better tire...
