I'll relate my recent, very personal experience. My front, stock size tire, had 2ozs of wheel weights determined by a spin balancer from the local Cycle Gear store that I personally balanced. Didn't have any balance issues, just wanted to see if I could do away with the external weights.
I tried the dyna beads, installed 2 ozs based on that chart, removed the external wheel weights. Got up to about 65 mph on the hwy I commute on twice daily, had the WORST tire bounce/shudder, whatever you want to call it. Went home, and reinstalled the wheel weights, re rode route, no problem. Took tire/rim to CG that weekend for a balance re-check, with the wheel weights removed, dyna beads in, the spin balancer showed a need for 2oz of wheel weights. I marked the spot where the weights needed to go. Added another oz of Dyna beads, no change and the balancer still highlighted the same spot needing weights.
I know others have expressed success with the weights. I watched/read all the research I could find, wanted it to work, but no way on my bike, on my tires. I also used the beads on the rear tire, same results.
I'd offer you mine for free, but they are loaded in the tire, might be a few months before I can get them out
Of course, YMMV, some settling of contents may have occurred during transmission. No implied or expressed warranty. Your volume may need to be adjusted, don't take any wooden nickels, yada, yada,
