First set was a PR
3 - mileage was less than 5,000 they had good traction but were smooth when I replaced
Second,through 4th sets were PR4 GT - also ran them on my K1200S - wet or dry good feel, response and decent mileage 4,500 to 6,000 depending on road surface and throttle application
Metzeler Roadtec 01 - great feel through 6,500 miles then became noisy but lasted until 8,000 - again dependant mostly on road surface. Wet and dry performance as good as PR
Continental Road Attack 3 - altered handling of the K1600, it would weave at certain speeds and shudder over 85, hey did not like wet roads - had them removed at less than 2,000 miles for Dunlop RS III
I'm on my second set of Roadsmarts - first set was was swapped out at 6,200 miles only because it was another 1,800 miles to the next dealer- wet and dry performance as good as Michelin PR
4 GT and Metzeler Roadtec 3, maybe a little better. The second set feel the same but the balance seems to be off. I put 4,000 plus on them from Anchorage home and they still have at least half the tread.
I run 42 PSi front and Rear and check pressure every other day
