Goodyear tire pre-mature blowouts/tread seperation

Had a bubble on sidewall of one Marathon with maybe 1500 miles on them. I was warned about these tires on another web-site. Took all the precautions including TPMS. I called GY and they credited me for all four tires toward G614's, after inspection by local GY dealer. I've heard some have problems working with GY, but all went well for me. Maybe it depends who the CSR is that you deal with.
