I drop four and take them to the tire shop. If I had a tire changer and balancer, the rims would never leave the yard.
FWIW, finding a tire mounter that is involved in his work and knows his stuff is not easy to find. These guys are paid squat and their interest is only as much as personal work ethic allows. I have a couple of shops that service my wheel work and I trust both to do a good job. It hasn't always been like that, I got back an aftermarket German sports rim, once, with over two pounds of lead stuck on it.
