I have an Chev 3500 farm truck that has 225/70/R19.5 tires on it. I want to change out the fronts. Most tire shops I have called won't work on the 19.5 tires. The ones that will are saying 25-35 per tire to dismount and mount (and balance I think). Question is whether for these larger wheels, do they typically have machines like car tires or will they use spoons and do these manually? Maybe a dumb question, I just don't know and a couple said it's alot of labor so made me think maybe they do these old school. Also form youtube I see some guy using beads to balance. Any thoughts on that approach for balancing on a tire like this?
