you can easily make a balancer, and a bead breaker. if you want to do the work yourself, the money you save will more than cover the cost of equipment.
go get a large fuking pole, like 8 foot, 3 inch diameter or something, like a streetsign pole. get a hinge and mount that to the framework in your garage. mont a metal spade on a hing on the lower section of the pole.
now you have a very long lever to use to break the bead off the tire, just put the tire on some 2x4's so you do not damaged your discs.
a balncer is truly easy to make. even gp teams use a static balancer.
if you dont want to do the work, well just take it to a shop. if it makes you feel better to spend more money, take it to a dealer
