I have he beads in my '62 Lincoln. The car has 20" rims with 40 profile tires. Dyna beads are not recommended as the sole balancing method for tires with that short of a sidewall. The tires are balanced OK, but still had some vibration. I left the wheel weights on and installed 5 oz of beads per tire. They call this a maintenance amount. They did take out most of the remaining vibration. I'm happy with the improvement they made.
