Yeah, I also run tubes.

I forgot about the tire migrating on the rim until someone else mentioned it. Watch for it at low pressures or you could end up with a destroyed tube. It gets worse as the tires age and the (bead) rubber goes from tacky to slippery. This year I'm going to try using a bit of tubular glue on one set of wheels that always has problems. Simply raising the pressure is not an acceptable solution for me.
