tires before finding a set of four that were (barely) acceptable in terms of vibration compliance. I'm almost sure that 'hop' you were feeling was because the tire was either out of round, not force matched to your rim, or both because I was experiencing the same thing.
Even still, the tires are really inconsistent and they flat spot like crazy!!! After all the drama I went through with these things I'm only marginally happy with them, at best.
