Just my opinion I have had three sets of Goodyear MTRs the second gen ones like what you have. The first set wore down nice and lasted pretty good, this set I got when Goodyear first came out with them, numerous wheeling trips and hwy to get there. Second set was good till about 60 percent tread left , developed death wobble. I changed ton stuff , then went and bought another set of MTRs. Death wobble went away all was good. Same thing at around 60 percent again, changed some stuff rebuilt front axle , etc etc, bought new tires all is good again. With all this being said i wheel on these tires pretty good I live in Colorado and go to moab mulitie times a year then I run low pressure in them and have been none to hwy drive with low pressure. I have two buddies that also run MTR that have developed death wobble once they wear down. We are all running 37 and larger and driving hwy speeds. Wobble seems to come on about 40-50 mph range, no amount of balancing could fix any set. I no longer buy Goodyear.
