Most driveshaft shops can check the drum to see if they are out of round or even a machine shop that does engine balancing.
But the tires could still be suspect. I always run the wheel on the balancer to see if it's good then mount the tire and if it's not close to even dismount and spin it until I get it as close as I can. Takes time though. In the end go with the balance beads to keep a constant balance int he tires as they wear.
