It is more about quality of work, than price. There are a lot of variables. How much would you expect to pay to get a car up in the air, remove messed up lug nuts, free wheels frozen to the hub, dismount, mount a set of 335/25-20 run-flat tires, deal with tpms, clean corroded bead seats, inflate to the correct pressure, balance with tape weights, hidden behind the wheel spokes, reinstall on the car, torqued to spec by hand, do the paper work, tire disposal, insurance, all the other overhead, and only charge $12 per tire??? It is never a great investment on the installers price sometimes. I charged $25 per tire, for that car, and it wasn't worth the effort, but I still did my best work, without damage, just the same. You can pay more, but you can't buy better.
