I bought a tire changing equpment and changed my first tire today.
I didn't bent a rotor, didn't scratch the wheel.
It's not bad at all.
if the dealer charges you $50 for mount and balance, I think it's worth changing my own tires.

and yes, it comes with a balancer. And I think it works damn good. There is so little friction, it took the tire good 5 min to come to a complete stop, after rocking back and forth.
