I bought 16.5 wagon wheels from summit, the US Wheel brand, and the goodyear mil-oz tires didn't seat like a "normal" tire should. Usually when I mount tires on 15s or 16s, the bead will seat with a "pop" and I know they are seated. The tires are bais ply an rated to 30 psi - and I know I put more than 40 in when I did the first air up. I bought these to run my used bias HMMVV tires for memorial day weekend, then I might clean up my H1 wheels and switch to a dually front hub to run them. When I aired up these tires, there was no pop, of course there is no safety bead on a 16.5" either, at least not these. The rim looks like it cold be sticking out a bit too far from the bead of the tire compared to my 15s, but there is no air leaks, and there is no more expansion of the bead. It's pressed all the way against the lip of the rim. Is this the ****tyness of 16.5 tires? That the tire wont hard seat to the rim, and basicly only the air pressure is keeping the tire seated against the rim? I never done 16.5"s before, so I just don't know their characteristics.
