I have the tech and lux package and the tires on my 19's have been balanced and road force balanced multiple times in the 4k miles I have on them. When on the freeway or at about 25 mph they chop and sound like a bent wheel. I'm furious to say the least, this is unheard of from a passenger tire. I have seen issues like this with my heavily cambered performance tires on past vehicles. Anyone have any issues from these tires.
