Mounting/Balancing can add up quite a bit - especially if its for 4 tires. Assuming they do a road force balance, I'd certainly take the slightly higher price per tire (as long as we're not talking $30ish more per tire). If all they do is mount the tires then forget it. What are you supposed to do with 4 unbalanced tires?
