I can't speak to the perceived connection between leaky hub grease and tire creep (seems unlikely) but 105 psi seems high for a hookless rim. I have a bike with Weinmann hookless rims mounted with original Schwinn Super Record tires, and 85 psi is the upper limit before they blow off the rims. At 80 psi, the ride is just about perfect anyway.

While riding home from work yesterday, I looked down at my rear hub and noticed a large amount of grease collecting on the non-drive side pressed in cap (Campag NR hub). About 2 minutes later my rear tire crept off the rim (Pasela TG wire bead on Weinmann hookless rim at ca. 105 PSI). Are the two events related? I.e., are there asymmetric forces one could associate with a slowly unseating tire which would result in grease leakage from the hub? Or am I looking at two separate events with uncanny timing? I haven't yet pulled the hub for other clues.

I posted this to the BOBs yesterday where it got no replies, so my apologies if you're seeing this twice, or if the question is ridiculous.
