No you tube videos for me. As for the USA you have look at the tread sideways to see it. If you look from the wheel looking into the wheel well after the shoulder blocks the first tread red block resembles a u, they center one resembles an S, and the next one resembles an A.
I currently don't have any worries about them being lightweight, that was one of the big selling points for me. 3750# carrying capacity and fifty thousand mile tread warranty which is the same or better rating and some tires weighing 14 lb more a piece. Time will tell I guess, only have a thousand miles on them currently.
