I never said better was last longer, I am talking grip, wear, handling. I don't like the metzlers because there is no tread in the center. The first Z6 rear I took off was thinner than I thought in the center even though it was down to the wear bars.
How the tires handle when worn counts too. If the rear gets a flat spot, leaning over can be odd because the edge. Once leaned over they seem to be fine. The PR3 on other bikes seems to wear more even or keep its round shape. I have only had my R1200R for a few months, so I don't know about other tires than what came on it when new.
PR3 has tread and wear bars in the center. PR2 is the only front tire I wore out the sides before the middle on my RT. PR2 on the rear of my versys still has a round profile after 6,000 miles.
Right now we have snow and temps in the teens Fahrenheit right now, so all I can do is talk about riding......
