Road trip and two blow outs on Goodyear Marathons

I got seven years out of the last set of Marathons on our previous 5th wheel. Noticed a very slight bulge in one and replace all five. Then two years later traded for a TT. When the Chinese brand tires get a little age on them, I might give the Goodyears another go or try the Carlisles. I've seen old Carlisles worn down to the belts and still working hard.
