I have had better for cornering tires for wet conditions, but in all other categories it out performs any other tire I have used.
I can hang off the seat, lay my VN900LT over until the engine cradle tubes scrape the ground and the tires hold on dry road. A sticker tire would be pointless. The shape and tread design work well on freeway grooves and cracks and lain line dots--very little "shimmy".
My next tires will probably be ME880's as well, unless Metzler makes ME888's for my mc by then.
I mounted these on my Burgman 650, and I've been spending as much time as possible heeled way over in the canyons. I also commute 300 miles to Arizona on the bike once a week.
These tires easily take a stock Burgman to its cornering limit, and when I upgraded my suspension to increase cornering clearance, these tires shrugged off the increased lean angles with traction to spare.
At 2,500 miles in, they appear to be wearing well. Unless they begin wearing down fast really soon, I'll be happy with their durability.
As I'm in SoCal, I haven't rated their wet traction, and likely won't.
Pull a camper behind my R1150 RT and last rear tire got 9000+ miles on it. Should have changed @ 1000 miles earlier but was still just ok. Have used them on my previous R 1110 RS which I also pulled my trailer & got great mileage. Only tires I buy. Great prices.
I love my Tourances. Best tires I've ever put on my VStrom 650. My rear tire lasted 9200 miles and still had close to 3/8" tread, when a nail ended its life. Needless to say, I've bought another one to replace it. Comfortable & reasonably quiet on the highway. Great handling in Colorado twisties. Very good traction in heavy rain. Competent enough on dirt roads to keep me from killing myself. Only thing I DON'T like is that Tourances tend to flatten off in the center with wear, leaving them rather goofy looking. But that's a pretty small peeve.
