It looks like Carlisle stands squarely behind their products! I contacted them on Monday morning, explained the problems I was having. New replacement tires were delivered to my door on Thursday afternoon.
I mounted them this morning, with tubes this time. I doubt I'll have any more problems with sidewall bulges. There may have been a defect with them to begin with, there's really no way to tell at this point.
I checked inside the old ones after removing them, there was no visible damage, although bulges were visible inside as well last night. This morning, whatever air remained in the bubbles was gone and they are smooth inside and out. There was obviously damage between the plies for air to be able to travel like that.
