The only issue i have had out of new set is getting tires to balance. There was mud in the rims, and once that was cleaned out, they ride like a dream. I had to explain to the discount guys how balancing a tire with mud on the rim was assinine (boy did I feel like I was channeling my grandfather). Mind you, they were not caked with 20 lbs of alto mud, more like sludge from my gravel road that had been building up in all the wet weather.
