I agree exactly with what you wrote above. There is no substitute for top quality tires.
SAM's Club covers more territory than Costco and is also a great source of top quality tires at the same prices as Costco. My local club knows me so well and I have bought so many tires and batteries from them they provide VIP treatment when they see me arrive.
We do differ when you got to the part about Goodyear tires. I won't buy one. It is true that Goodyear replaces blown RV trailer tires and pays for the damage very frequently but if the owner purchased Michelins or BF Goodrich tires instead he wouldn't experience the blowout or trailer damage.
Nice to hear others are willing to buy quality!
I should have continued about the Goodyear tires. My Dad's tire problem was from the tires that came on his 96 Hitch Hiker. The tires he replaced them with are a different model G rated tire. Those tires have given no trouble with many thousands of miles. Good year tires came on 5th wheel US made E rated, went to the G after 6 trouble free years and many miles. I didn't like the way a lot of trailers come with so little carrying capacity that is why I went with the G. Goodyear does make some crappy tires also but these are very a high quality US made tire. If these get thru 6 years with no problem I will buy them again. I have two years of wintering in Cal and AZ coming from WA state. If not I will go with Michelins. I have used Michelins or BFG on my trucks for 30 years with no problems and great mileage.
