I called Costco to verify that they carry BFG AT KO 295/75/R16's. Guy on the phone said they don't stock them, but come down and order them in person and they'll arrive within 5 days. Great. I'm in no hurry and the price was better than anyone I called. So I drive down to place my order. Tire flunkee explains to me that if I already have those tires on the truck, they can order and install them. Otherwise, they can only install OEM spec tire sizes. It's a safety issue. I'm willing to sign a waiver. No go. It's a safety issue. I can walk inside and buy a pallet of whisky and drink myself into a coma, which apparently is not a Costco concern, but when it comes to tires, they're looking after my best interest. What's just precious is that it's not a safety issue if they are replacement oversize tires outside of OE tire specs, but it is a safety issue if they remove OE spec tires and replace with oversize. Gotta love that logic. If you're looking to upgrade your tires to oversize, apparently Costco doesn't want your business.
