They are off a toys r us truck my neighbor had. I got them to fit on the beadlocks. They handle great off road. They are really noisey. They are about the same hight as jumbo kongs and alot narrower. They aren't anywhere near the weight of jumbos either so there isn't much strain on the tranny. I did change out my chassis so I have to get updated pics on here. Those pics are a little old. Im now using a rc solution chassis and not the tmaxx chassis in those pics.
