I don't want to stray too far from the OP question but here is a crappy video that helps display my thoughts, it was quick and dirty, but I think it gets the point across, you can hear me grunting when I was pushing down on the bfg to flex the sidewall. I know this is not scientific, but I have mounted enough tires in my day to know the difference in sidewalls(that's what he said...sorry had to). Pardon my 2 cents and out shop music, that side of the shop is country the other is classic rock, its a constant battle...radio wars everyday...sigh.
