So far I have 7K on them now, and on the previous F6B (sold)I had close to 10K and for all of them I run them at 40 PSI, give or take1-2 psi depending on the TPMS and hand gauge/ pump reading.

From the looks of it, and what I read of others is that 20K is the ballpark norm.

But most impressive is the handling in twisties, I feel more confident with the extra rubber footprint in the rear, so yeah after 17K riding with this tire in the rear I say it is a winner for me.
