I used stick on wheel weights originally on the 87 coach. The results were that over time the tires went out of balance and had to be rebalanced. Any out of balance, especially on the tag or steers messes up the wear pattern.
When I replaced that set of tires I was talked into using Equal. It costs about $10 per tire and the tires are always in balance when Equal is in them. That set of tires went 134,000 miles and zero unusual wear on any tire. I did rotate the tires twice.
I have Equal now. I know of at least two coaches that use Centramatics or their equivalent and I think the concept is the same. The problem I have with them is that on one set they had almost cut through the tire valve stem, a condition that could be eliminated by cutting the tire stem slot larger. But I cannot get past the economics of Centramatics. At the current cost you need to change a lot of tires and add a lot of Equal to come up to what you end up paying for them.
