Road trip and two blow outs on Goodyear Marathons

Sound guy, it's ok, even Goodyear thinks they're no good. You don't have to defend them. They're just tires....
My personal data is 3 trailers, 4 sets of Marathons, and about 10 of the 16 tires lost their tread.
Compared to countless other trailers and tires with no set pattern and no d lamination and far fewer tire failures and not the same repeatble failure mode.
