No gap here:



Do the current car tires that some of you are running; present a snug fit between the wheel's bead hump and the side of the wheel's bead flange?
I can tell you that yes it is a very tight fit. I generally takes more than 20 lbs of air pressure to seat that bead on a CT on a GW rim. And when you break it down it takes considerable pressure to break the bead.
