That is odd. There's obviously some quality control issues at play. I would lean more towards Schwalbe in my case since Conti Ultra Gator Skins and Bontrager Race Lites went on perfectly.
I was able to get the Schwalbe's seated by inflating slowly and pushing down on all areas of the tire that wanted to work off the rim, but as soon as I would hop on and ride they would blow. Bad news if you were going downhill when that happens.
