I had a Mefo on the back and it didn't inspire confidence in the twisties. Went back to the TKC. On dry pavement, the TKC does surprisingly well. Wet, it sucks, like any other knobby. And we all know the wear sucks.
I'm tubeless now and can air down more for better off-road traction.
Some guys turn the front wheel around when it starts to scallop, to extend the lifecycle.
