I've been using Dyna Beads for about 10 yrs now & w/ never go back to weights, no tire cupping, no wobbles on both bikes, a GL1800 & on my FLHTUC..

 

What about TPM Systems? Will the beads affect or cause damage to a HD TPM System??

 

Quick search reveals this cut and paste from the FAQ of the Dynabeads site:

Most TPMS sensors that thread onto the valve stem, such as the Pressure Pro, will require a filtered valve core.If your wheels have a TPMS system that is an integral part of the valve stem, Dyna Beads will not cause any problems, but you won't be able to install the beads using the Applicator.

 

with tpms, you would have to break the bead on one side to install.
the tpms sensor hangs close to the rim so i would suppose the beads would not interfere while running since the beads are thrown out to the tread area.
however, if the beads cause dusting, it is possible to block the sensor holes so i guess that is what the filtered stem would try to eliminate.
