FWIW, my experiences with Dyna-beads in motorcycle tires has been GREAT!
I've run the same beads in 3 different sets of tires now.

 

The only problem I have with the beads on my work truck is that when I check tire pressure seems like everytime i get beads in the valve stem and get a leak. It is the only drawback i see. The tire balance should not be an issue until over 45mph anyway. Mine were out of balance by 1.25 ounces on each wheel and it didn't show up till 70 mph.

 

Are you running the filtered valve cores? If not, then that is the problem.

 

yes filtered valve cores they came with the kit.....was thinking might have something to do with the 110 psi in my tires.....but not sure, although I did watch the tire tech install the cores in my valvestems.

 

I agree also your tires get a visual inspection once in a while, why I won't run nitrogen, just cuz your tires hold air does not mean they are good and you really trust that kid doing and oil change to know if you tires are good. I left from and oil change and they gave me a check sheet said tires were low,, air added pressure now at 32 lbs, they they proceeded to give me a tread depth reading, but if they opened their eyes they would have seen the dry rot or maybe they did and didn't want me to try to get tires after only 2 years and change.
Rotate and balance for 32 bucks is a good deal.
