Mounting and balancing tires costs around $20.00 per tire.
So for mounting and balancing 4 tires would cost around $80.00 and then there's the cost of the tires themselves.
For example if your tires cost $75.00 each and you have a $20.00 per tire mounting and balancing fee then the cost would be $95.00 per tire.
So to mount and balance all 4 of those tires it would cost $380.00 and then there's some tax.
Different size tires cost different amounts so it's hard to say what it would actually cost you to mount and balance 4 tires.
The tire place also factors into the cost and the cost of your sales tax in your area.
But for a light truck or car figure on $400.00 or less to mount and balance 4 tires but the cost can either be a bit more or a bit less depending on the vehicle and the tires you buy.
