Not sure if many folks outside of commercial trucking have heard of this great tire balancing product, Counteract Balancing Beads. Unlike products like Equal and other powder stuff that can gum up when in contact with moisture, especially in the valve stem, Counteract is like little glass beads that have a negative charge and they cling to the areas o the tire where they are needed. They are large enough that they will not get stuck in valve cores. I have used this product in my commercial vehicles and it is great. And it is reusable from tire to tire. Might be worth taking a look at by some here. Throw in a bag when mounting a tire on a rim and never have to spin up a balancing machine then or ever. On my present semi, I have gotten almost 200,000 miles on a set of steer tires, and they still are good for more miles. I am using wide based singles on the drives, and based on tire wear, they will hit 400,000 before needing changed out. That is not quite an apples to apples comparison to tires we put on our pickups, but it shows the product does a great job.
