The number 59 was stamped on all the "band" looking half of the wheels. I also found 59 stamped on the backside of the deluxe heater housing.
He was lucky, but he put chains around them and used the air hose from a distance (while I was hiding behind the shop).
He did know what he was doing. Every so often, during adding air, he would inspect the process and bang on them with a hammer. (again while I was peeping from behind the shop)
But he never had an incident during the whole process.
I am just hoping the longer they stay on, the safer they will be. The old ones had probably been on there 20 years.
