When I first read (not in this thread) that the bolt circle diameter had changed, I went out and put my 16" spare on my truck. It's from a '90s truck, so it fit OK. I'd've been in big trouble if I'd had a flat and the wheel didn't fit. Of course, I went camping several times with no spare at all...this truck came with the spare wheel only. I can't make any sense of that at all. Got a blowout? No problem, there's a spare bare wheel right here under the truck!
