I had the rope on for the first time it went into the water but I seen how stable it was and knew the rope wasn't needed.
As for the tires with the pressure in them. They are horrible on land filled up
Very bouncy and you only have the center of them contacting the ground. I did actually have a problem with them blowing off the bead of the rim. I think the truck is just too fast and weighs to much. Since this wheel combo works so well I'm just going to go ahead and glue the tires to these rims. I actually like the look of these wider tires and wheels. With the tires glued and low pressure in them they should get great traction.
