Road trip and two blow outs on Goodyear Marathons

Thanks for all the replies. I'm going to cut my nose off to spite my face and go with anything other than Good Year tires. Shame on Good Year for stiffing me with an obsolete tire while on the road traveling cross country and shame on Walmart for selling such an inferior tire. I'm going to go the rest of this year on the new Marathons and then switch to the Kuhmo 857 "E" rated tires that hold 65 psi.
