I hired a kid off the reservation in 2012 to run the tires in the shop. He couldn't get a tire off on a truck so we gave him a 8 lb shot filled hammer and said "give it a shot under the truck and it'll come off. Laying on his side, he took a swing, it bounced into his face and broke his nose. He went to the clinic on the reservation and never came back. It bounced for sure.
