He has the weight redistributed, and his form is good going into the left hand corner. He's gonna get tired, and the passenger may run out of patience, otherwise, gonna be really funny looking tire wear. I can roll to a stop and set my outside wheel(a 250 dirt rig), so with a little space to maneuver I bet he can avoid rim damage. But I agree, duct tape the remains of the tire, and anything else handy on there, give yourself a little more room for error. I rode home 6 miles on a bicycle tire packed with pine needle.... Just not very fast.
