Thanks Jon, I think I brought this up once before, but I've been driving and working around cars from back in the mid 50's. I rode on a lot of bias ply tires, my first ride on a radial tire was a set of Michelins on a '75 triumph TR6 I'd bought new for my wife. I remember some bias plies having a very slight thump after setting over night. But I never saw any that were as bad as those Power Kings.
