So back to the 19.5 debacle .. Had the tires taken off my polished wheels and put on the steel wheels, Balanced with weights and its decent to drive now with minimal vibration.. It's a dump truck so I expect a certain amount of a rough ride. Took the F450 Limited that has the new Bridgestones on it back to the shop that installed them.. It had lead weights and centramatics and it felt like the tires were square.. It was nothing short of awful to drive. .. The original shop took the weights off, removed the centramatics and put bags / beads in the rears... I drove it about 60 miles and it was absolutely miserable .. You couldn't leave a coffee in the cup holder without it splashing out.. So today.. Back to another shop.. Remove rear tires and suck out the beads.. rebalance with weights, no centramatics and re install.. Still sucks to drive... This truck was silky smooth with Continentals but they wore out at 20K miles. Im tossing the back four tires and putting rib tires on the back that match the fronts.. Its getting to the point where I'm going to get rid of the truck next...
