Every truck tire retailer should have a safety cage. The mounting area on the rim should be cleaned properly and inspected for cracks along with the ring, then mount the ring on the rim with out the tire and make sure it seats correctly, then there should not be any problems. Just make sure and use a cage and an air inflator that clips on to the valve stem so it will inflate the tire unattended, this way if the ring comes off in the cage it will be knocked off and no one gets hurt. During the early 60's I worked in a Foreign car shop that was next door to a truck tire store, one of their employees got killed by a ring coming off, the tire was not in a cage.
