when the seperation of your tires occured, what was the psi that you were running in them?? the reason i ask this is because on the website, they stearnly warn about not running enough psi in them, the tire will actually melt the vulcanized rubber holding them all together, and the tire will seperate from the carcass....by the way...it only took about a week and a half or so to get my tires at my house up here in BFE country, mi
