I have had tread separations of 2 of the 4 Marathon ST's. They are LR-E. The other 2 were showing signs of tread separation pending, namely they were not round anymore. I took them all to Goodyear tire dealer and had them replaced in the last 3 months. They were 3 years old.
There is no higher capacity ST tire available. These tires are covered when not in use., Always run at 80psi and monitored with a TSPS system. So save the blah blah about not taking care of them. My rig has been weighed and is not overweight.
BTW, had I not had the TSPS system, I would likely have a damage claim against Goodyear. They should give away one with each set of tires IMO.
