Had a bad blow out .And tired of reading 1000 post on tires

I lost a tire last fall and after a lot of research I put on four Goodyear 614 RST (235/85 R16)tires and I'm very happy with them so far, as far as Michelin is concerned I was a loyal customer for much of my adult life but last year after one and a half years and 18.000KLM's all six of my LT235-80R17 started to rot and after a solid week of fighting with them they finally settled on giving me only 70% off on replacements I'll never deal with that company again!
