I have talked at length with CC about that, DBLR. They did carry Goodyear but the new rating system put the Goodyear's they were using below the carrying capacity of their units, so they switched. I don't think they wanted to.
That said, saying "Goodyear" isn't enough. The Marathons are pure junk. The G614's are good stuff. So it matters which one you mean.
Still.........CC (or anyone) should offer the G614's as an option. Yes, that would mean they'd have to warehouse two sets of tires........which they don't want to do. BUT.........up until recently at least, the Champagne came with G614's!! Add all that up, and it's confusing why they won't offer what the folks want.
I will say that the Westlakes that they are using are 14 ply tires, and are Chinese but not junk. I'd prefer the G614's, but at 4,000 miles mine are ok....especially after I had the axles aligned. I do think that secretly I wish they'd wear out (quietly!!) and I would 'have to' go get G614's, though! I keep worrying that even those will soon be shipped overseas.
