I bought a set of Nitto 555's a few weeks ago. Felt a vibration in the whole chasis starting at 85 and getting worse as I got up to speed. Finally got it in to check the balance again. Asked when they got their machines calibrated. He said they just did it and the machine mine were done the fist time on had a bent shaft replaced and was 1oz out to boot. My worst tire was 3oz out insde and 1.5oz outside. They said one machine had 256 miles on it that is a lot of 3sec. balance spins.
