I'm about 5000 miles from needing new tires and want to get as close to factory balanced as possible. What's the best way to get there? I searched the forums and read that finding a shop using the Hunter GSP 9700 machine could do it. Is that correct, or will I need to take it back to the dealer, or is it a lost cause and I'll have to live with ? More than likely I'll be going with the same Michelin LTX A/S tires that came with the truck.
