Gen 4 SZ5 Alloy wheels and 215/75/15 Toya Tyres - Balancing proving challenging

This website has lots of info about balance beads...

www.dynabeads.co.uk/

Ive just bought some ceramic ones from them to try after mixed results with the plastic ones from devon4x4

Does the prewar car have inner tubes?

My tires also has a balancing issue at approx 55 mph / 80kmh.
I added a thicker shim to the lower kingpin and that improved the wobbling about 50% so that might be the issue, I have not done the complete king pin service yet.

Friend of mine balanced the wheels with the cone to perfection acc to the machine...
Maybe I could mount the wheels on a machined spacer with bolts next time to see if there is a difference.. The wheel will be centered on the spacers machined center hole.

Yes it does.
I've heard of people using beads on very old cars with tubes before, but never actually met anyone using them... I therefore thought it might be a form of snake-oil

Ah OK didn't think you could use them with inner tubes, I bet it is a pain getting them balanced

I have Blockley Tyres just up the road from me - they specialise in classic and vintage car tyres and supplied both the wheels (which came from MWS ) and my tyres for the car, they can balance them so theres no big issue actually getting them balanced, but its further periodic costs and maintenance, so I'm now interested in the beads and how good they actually are.

As with all these things I find it better to speak to people actually using the product rather than someone trying to sell it, therefore getting first hand experiance from an independant non biased source

I did not find anything on dynabeads on how the interact with the tire pressure sensor. I understand, the the beads are on the outer circumference, but they generate dust, ...

Thank you for your comprehensive reply!

Well... I went ahead and bought some from Dynabeads UK - not for the pre-war car but the Jimny (the pre-war motor is way off being driven yet)

The 4x4 beads are bigger and, as you say, won't go down the valve stem so I've elected to use the smaller beads, the only difference being... they're smaller - probably easier to lose when the tyre gets changed though.
All the reviews I've read anywhere, are really very good.

I will get round to putting them in the vintage tyres once I've convinced myself

In The Olden Days, balance weights for wires were small cylinders with a split up them that you slipped over the spoke near the nipple, and weren't obtrusive, sort of a rich man's version of just winding a bit of window lead round the spoke (which was how I used to static balance motorcycles )

If I remember, I'll have a look at my New Motorcycle, it has wires, and I don't recall noticing any balance weights, but the rims are made from "corrodamatic" alloy so they could just be stick-ons that I haven't looked for.

My dad first used a form of balance beads (lead shot in oil in a plastic torus) back in the 80's. He got rid of them. Here is an article from 2014 about bead balancing and the issue of not being able to balance laterally. Not sure if you would have this issue or not as it seems its prevalent in low profile tyres.

Wouldn't tyre slime have the same effect as beads? That doesn't wear the inside of the tyre (or "tire" if you have a Gen4) and it lubricates the inside if you have a puncture.
