I had it done to the new Michelin tires I purchased years ago for my truck. Changed the amount of weights needed to balance and really made a marked improvement to the feel driving down the road. I ended up finding a place in Florida to get it done. I don't understand why so many tire places have stopped doing this, it took about 20 minutes per tire, but I paid what they charged and felt I got my moneys worth. I wouldn't mind finding a used piece of equipment and having it for my own use and for friends. It does make the tire roll smooth and extends the life of the tire.
