These on my truck I had removed last week,Sidewalls were splitting out and the truck had developed a noticeable ''Death Wobble''even at 55 much less 70/75 on the interstate. Has anyone encountered this failure or perhaps can shed a light on these puppies? MFG'ed in 2015, I have about 61.5K on em' Judging from the threads another 10K I should have easily gotten! All 4 failed BTW ! Thanks monkeys!!!
