I had the tires on my Silverado all trued and balanced. Man what a difference. You would think that cutting rubber off would decrease the life of the tire but it actually doesn't. Plus they balanced the tires on the vehicle. I think this is the best way to go. It balances the entire assembly. What amazes me is that they do it all by feel. No fancy computers or gadgets. I now have a nice smooth ride. Here is a picture of them truing the tire. Here they are balancing the tire on the truck.
