Hi- So, I've done 4 races this year with Stans Iron Cross wheels, setup tubeless with Clement MXPs.I weight 167 and have start with 24/26 lbs and have progressively moved up to 32/34 lbs.  Even this weekend, with 34 lbs in the rear, i lost enough air that I had to hit the pit to top off the tire. I measured the pressure post-race and my reading was 48 lbs- which exceeds Stan's 45 psi recommendation.   So at this point, it seem my options are to run 42/44, and try my luck again, or put a tube in the rear.   Does anyone know if the 45 lbs limit applies when you run tubes in a Stan's rim? Anyone with similar experiences with Clement MXPs and tubeless?  Any other thoughts / recommendations? Thanks! Pat See More
