So the best education here is to never buy Goodyears. We tried everything including road force to get these to stop shaking and after my frustrations got the best of me I pulled the pin on some Toyo MTs. They ride amazing for a 10 ply and are the same for noise as the dura tracs In the end my vibration is 90% better as you can't expect perfection from mud tires. I always have the WK with studs for the really icy and dicey days
