These are the gadgets that have loose weight and balance the wheel as it spins..... is this right.....
When I was young I spent some time running a tire store... . and now and than we'd get a tire in that was not in balance would shake the vehicle... We'd dismount the tire... . and usually find small balls from the excess tubeless liner that was loose and spinning in the tire... . We'd remove it, balance it and the customer would go down the road very happy... .
I personally don't think these things can work... in addition as you speed up or slow down these weights are going to either be ahead or behind the spin of the tire as they speed up and slow down... . this of course would tend to make the tire out of balance...
If someone has a better answer I'd love to hear it... . other than the stuff published on the web sight of the vendor..... Common engineering tells me that something that accelerates and de-accelerates needs a good approach to balance.....
