We visited Eastman House a couple of years ago... an odd man with a nice house.
I've had a problem with Schwalbe Mondials folding tires blowing off what is probably a too-wide rim (Velocity Psycho) but only the rear, not the front. The folding tires seem to go on a bit too easily. The wired version doesn't blow off but has a flat spot (manufacturing defect).
Don't know why (other than cost) but the Mondial wired has an inferior compound and sidewall as compared to its folding brother.
