Query: Out Of Round

Purchased these tires because of all the rave reviews, however after installing themI noticed as if the tires had a bump on them that made the bike ride like it was going over a speed bump. Switched the tires around ( laborious ) and problem was not solved.Upon spinning the tires, you could see they were "out of round". One was worse than the other.Quite disappointed with these tires since I paid alittle more than some of the others onAmazon hoping it would be a better quality tire w/o problem. I would rate this a minus starif it were available.Will install old tires back on and discard these.Out $$$
