the 180's I had on did not feel as planted as the 190, up at highest speeds. seemed a little bouncier and perhaps not as 'heavy' feeling. hard to describe, but I DO prefer 190 at higher speeds 160+. I first I thought it was all in my head, but after going back and forth a few times, I can tell the difference. however it is just barely noticeable and never felt UNSAFE... just not as 'planted'. turns GREAT though! if I HAD to pick one or the other, personally I go 190 cuz I like the high speed stuff
matter of fact I have the Diablo Strada 180 on right now. yep - no 190 for that so I was stuck with 180
I guess milage is good... I went to Arizona and back from Iowa and not much flat spot 3500+ miles, but I didn't do tons of 'spirited' riding. I got to about 160 a few times but with all the baggage strapped on, it was no fun wind-wise so I didn't take it higher. tire feels good and takes bumps well, seems plenty sticky - I did a track day on it couple weeks ago and after my initial paranoia went away, it felt as good as teh regular diablos I usually use. The ONE THING I noticed about the Strada [and maybe this is ANY touring tire, I don't know] is with the softer ride and deeper tread it can warm up and feel kind squirrelly, almost gooey at low speed like 25-35. after being on it for 12 hours, I got to denver and I could have SWORE my rear tire was FLAT the way it felt. I pulled over and checked it and it was at 45psi - up from 40-41 where it started, and was perfectly fine. I thing the flex/skew from deeper tread AND a not so tight bump absorbing carcuss made me feel that. it's sticky seems as good as anything, rarely spins on hard take offs [I run 35ish psi usually] and much lower heatup needs than the Dunslops or those crappy, icey HPX tires. I can't judge their milage really since I haven't ridden 'normally' on them, but they did thier 'road' tire job wonderfully. I doubt I'll get them again. I just prefer a tighter, sportier feel tire. I'd get them for another long trip though. personal preferences here
