38, 41 is what I run in mine also. Good handleing tires, wet or dry. though slow down for the wet please.
I got 7k on the back tire before this change. still have front on. Started getting the low speed wobbles. New back, wobbles gone.
I am heading out to Rockies Gold next week, so wanted good rubber on the ground. If just around town and such, I might have kept old tire a bit longer.
