I used Metzlers on a Deuce, rear worked good, front cupped badly on the edges, 10K miles was the life of both. Put Metzlers on the V-Rod, rear cupped badly on the edges and lasted 10K, front has no cupping and will probably go close to 15K. I've gone back to a Dunlop rear. Gave me 10K with no ugly wear pattern.
I don't do enough twisties to wear out the sides and I avoid the rain if possible, which means I might miss 30 days of riding out of 365.
For all you guys putting on bigger tires, why do you want to reduce the handling quality? 180 is optimum.
