I can't find them in a previous thread easily, but has anyone tried Dyna Beads ?

Trying to eliminate an annoying slight vibration at 55-60 and feel tradition wheel balancing doesn't last of you do proper mileage & actually wear the tyres down a little

Hello Jon,

i´ve used Dyna Beads to quite good efect on my Roadster (black DAYTON 7x15 wire wheels).

BUT: the vibration you have might well source from the car "flattening" the tyres whil standing static for a longer period.

Albeit those "flat spots" should disappear as soon as the tyres have warmed through.

So i can recommend Dyna Beads (no connections!) + tyre "shoes" when the car is static.


It doesn´t matter how fast it becomes, but how it becomes fast. laugh2

Numog, many thanks

Flat spots are a fair point too, but I did increase pressures to about 40 psi whilst we were on Covid lockdown

Did you remove the existing old weights (as recommended) ?

Not wishing to hi-jack this thread but I wondered about something like Dyna beads too. Before installing Auto Seal into my tyres on both the Roadster and the P4 they ran true without any vibration but no longer. Ambient temperature seems to affect them too. Anything over 120kph can be annoying but sometimes the vibration is not present at all.

Hope I am not stating the obvious but if we are talking wire wheels, I presume they are balanced using cone adapters to seat the splines on the balancer ? If not, the wheel will tend to run out of true which will adversely affect the balance. I've yet to find a tyre shop who has them, so we have 2 sets in the Wessex Centre which are lent out as required. Just a thought.

Jon: i left the standard weights (dynamically balanced on cones, of course! ;-) ) and just added the Dyna Beads.

It's a 3.7 on alloys as I wanted a change from wires (but I do have a set of personal 'cones' in my tool kit)

I tried Dyna Beads on my previous Plus 8 (alloys). No effect whatsoever. There is so much that can cause vibration on a Mog in addition to wheel balance. So I persisted sorting everything out I could think of and eventually got it pretty good.

How are the king pins ? any play when you jack the wheels up?

Have you checked the wheel alignment and the toe in?

Looking at the explanation of how dynabeads are supposed to eliminate vibration they are said to distribute themselves by reaction to the oscillating tyre innards but for that to remain effective surely once the tyre ceases to vibrate the beads would be free to re-distribute at random. Logically the imbalance would phase in and out but not be eliminated permanently.
I had the tyres balanced and spokes trued up on the S.S wires of the 4/4. Transformation was well worth the expense.
