Tell y'all something I learned a long time ago, now the first set of tires I replaced on the dump truck would not hold a balance and at some speeds with a car on the back it would bounce, just a little but noticeable, my friend at the shop told me to get them trued, he showed me when he jacked one set off the ground and you could see they were not round, once I got them trued they were smooth as glass. Works the same for them big ole bucky beaver ground grippers or street tires like above.
