Sounds like those Michelin's did the trick for you. If you like them just install another set and you know you can go another 10k. I would not try to keep the front another 2 or 3K because it just isn't worth another trip to the shop.I have 10,200 Miles on 2018 K1600B, I have the original Michelin Pilot GT tires. I noticed today the rear tire is almost wore out in the middle. The front tire has good tread depth, but has cupping on the sides. I check the air pressure on the 1 weekend of every Month.
