I've read some things about what you all are talking about regarding 5.5" vs 6.0" rims, and squeezing the tire and thus changing the profile.
My 05' 999S comes with a 5.5, and a 190 Pilot Power. A super sticky tire, (it's tough getting rid of the 'chicket-strips with this tire!) but I'm curious as to the proper profile for the tire. It must be OK right? It's Ducati OEM for god's sake! But I think that when I need new tires, chain, and sporckets, I will jump to the 6". Unfortunatly, I have to change to either a 520, or 530 as Marchesini don't make aftermarket rims that will take a 525, and cush-drives also need to be changed.
Any other feed back would be appreciated...Hommie
