My best buddy ran a set of 33" Dueler MTs on his 1986 Turbo 4WD single cab, and they were great for a while, didn't do any wheeling, just pavement miles, but when they got down to about 40% tread he started having all sorts of balancing problems and the treads became very stiff and hard, it rode like crap, became very noisy, and seemed to gain uneven tread wear over night. He always kept his IFS aligned and well maintained. With nothing else left, I blamed it on too much exposure to the sun as this rig is parked out doors.
