thats why I was thinking of using thumb tacks. I'd place them in the same locations on the left and right tires, simply punch them through the tire from the inside. Then put a bit of silicone glue to hold them in there. then just put the foam like normal and the rims. I think using studded tires on snow, you probably wouldnt have to worry about them being 100% perfectly even, they're gonna be digging into the snow anyway. maybe im wrong though, i've obviously never done this before. but I have a whole year to worry about it because I wont be using the truck in the snow this season. unless it gets warm enough to break the engine in and then snows again all of a sudden. lol.
