Looking at a set of 6 tires 245/70/19.5 for my Class A RIG w/Ford F53 chassis . The two shops in my town can't even get Michelin tires (seems to be a shortage). I was offered Bridgestone at one shop for 2600 and Prinx at the other shop for 1500. One thing the Prinx tire shop stated was they use "balancing beads". Is this a red flag? or totally fine?
