I've got Michelin Pilot Road 4 GT 170/60 ZR 17 [MC 72W] rear, and 120/70 ZR 18 [MC 59W] front. No great speeds yesterday through 350 k of winding roads, a few bursts early out of the corners but nothing like one narrow model Harley that ripped past me in one bend where I watched his rear tire notch over a half inch five or six times; glad he was on the outside.
These were nearly new when I got it 2,500 km ago, I think the whole thing rides perfect, other than I might adjust my rear pre load [?] a bit stiffer. I've had it out a number of times with a bit of frost on the roads, thought they were great, but almost entirely only on really good roads, a bit of grooved for asphalt surfaces and asphalt grooves and ruts, no idea how it will do on anything rough or heavy highway rain. I've brought it up to pretty good speed a couple of times, pretty hard couple of practice brakes, 120 - 130 k, real dirty wind overcoming a couple trucks, overall I think I can feel these tires working perfectly and for my moderate style I can't imagine anything being any better. I didn't take an initial depth meas. of either but they seem to be wearing a bit, will do that tomorrow. Even if they wear at a fair rate, I'll get them again.
