Either the tire was not mounted properly and was therefore not fully seated, or your tire pressure was low.
When you run a stretched tire you have to keep in mind that it is very hard if not impossible to tell if the tire is low on air by physical appearance. You need to be checking your pressures often to ensure it does not run low on air, as with any tire, stretched or not, that will cause tire failure and possible unseating of the bead.
