Are my tires supposed to rotate on the rim?

[maytag]

Mounted about 10 days ago. No paint on the bead. (I've got a pretty cool method for that, which includes a pack of playing cards, hahaha)

So im told this is, actually, quite common. Though I'd have never believed it.

I have to think it happens when they're cold, with low pressures (beggining of a session). I started my first session at 28, and the tires climbed to 40psi. So I bled them to 34. The next session they climbed back to 37, so I bled them again to 34.

Then there was lunch, and an extended delay (long story involving being recruited as an instructor for a beginner). The ambient temp dropped, and I was parked in the garages where it was cool anyway.

So it's quite probable that the pressures were QUITE low when I went out the last session. That could be when it occurred.

I dunno. I'm grasping for a reasonable explanation too.
