Hi Kev,

Yes you can if you look at the second link on my post ?

I think that Jake Wilson sell them too, I'm sure I saw them while looking at tyres.

They probably won't work so well for people that use tyre slime though....

When I ordered my tyre from Jake Wilson this morning (11/07/2012) I thought I'd try the Dyna Beads as well. My local tyre dealer doesn't have an issue fitting my tyres, however, they don't have the right gear to do a bike wheel on the balancer.

Not to get to technical, but centrifical forces are more likely to have the beads settle in "imperfections of the tyre's innards" then actual weight differences (path of least resistance).  A not properley balanced tyre vibrates, therefore I would think not allowing the bead to settle.  An example that comes to mind is a roulette wheel.  Even an unbalanced wheel will give you random numbers. Just a thought.

It's only a tryout and it couldn't be any worse than an unbalanced wheel/tyre. Most reviews I've seen have been positive and there's really only one way to find out anyway.

Will be interesting to hear the results.
I was setting up my Gear Position Indicator on the centre stand today and there was no doubting the rear wheel was out of balance, despite having weights on it.

The Dyna Beads went into the new rear tyre before I refitted the wheel on Thursday. Being the first time I've done this it took a little trial and error in getting the beads through the valve stem.

This time an oil/filter change was due so once the wheel etc was back in place I proceeded with that and also I lubricated the often neglected side stand pivot point.

On the Friday we went to Port Pirie for our usual shopping trip which means towing the trailer. With a 220 return trip it's a little to early for any comments re the Dyna Beads but so far nothing unusal from the rear end. I do have minor vibration on the handle bars but I've put that down to an unbalance front wheel.

This morning I put the Dyna Deads into the front tyre/wheel and  that tyre has about 4000kms of wear on it so I'll see what the beads do as far as that vibration goes and improving mileage (if any).

I good test will be the Border Ride which we are still on track to go for.

 Allan, I have done some study on these beads. When I get my next set of tyres from Jake Wilson I will give them a go. Some say you should have 45/90 degree valves as it makes it easier to fill. If you can get your tyres fitted you then need the starter kit to put in the tyre. One site I looked at said that if you get some clear tubing 500 mm long, you can put some beads in then with your compressor you just blow the beads in slowly .
See how you go. Cheers Adam

I found this little test to show you the effect of adding Dyna Beads to some 'out-of-balance' apparatus.

Seems to work fine....

Been using for the past 2 sets of tyres and have no problems much better than a bad balance job.

[Diesel]

The following doesn't seem to be a problem - but worth a read.........


Direct from the Dunlop website - •Dunlop does not warrant or give credit in any adjustment transaction for any kind of material added to a tire (e.g., tire fillers, sealants, balancing substances) after the tire leaves a factory producing Dunlop tires, nor will it adjust any tire that has failed as a result of adding such material.


Where'd you order yours from Oz?

[OzRider]

That's alright I use Mitchies 

Got mine in from Jake Wilson last time I ordered some tyres which after the WE will be again soon.

[alans1100]

Having ridden a mere 800kms over Friday 3rd/Saturday 4th August I have nothing negative to say about the beads.

The rear tyre has only a 1000kms on it now so it's to soon to tell re tyre wear.

The front tyre now has 6000kms up and the beads added at 5000kms. There was and still is some minor vibration from the front which I put down to an unbalanced front wheel/tyre but I'm thinking may now be more head stem bearing related.

[alans1100]

It's been awhile since I updated this.

Front tyre is now due to be replaced after a total of 13500 kms (8000 with beads) making it 1500 kms better than the previous unbalanced tyre.

The rear one has done 8000 kms and the previous unbalanced rear was 8775 kms and looking at my current rear tyre it will exceed that distance by another 2000/3000kms.

Are the beads as good as a weight balanced wheel? Since my local tyre fitter is unable to balance the wheels I'd say the beads are better than nothing.

I still have a very minor vibration on the front but that could be caused by the faulty RH fork seal.

The next front tyre will have the beads in from the start. All that remains now is see how far the rear tyre goes before replacement is due.

Thanx Alan,

Balancing beads r the way to go it seems - but not accepted by the industry yet cause they have to write-off their balancing machines.

I have been looking into the beads this last month and there doesn't seem to be a real local source.

Just bought a set of Mitchelins and want to do the job myself. Jake Wilson just shunts u off to the US site to buy the beads with a horrendous shipping fee of $40 to ship 5 oz of beads to oz.

The stainless steel balls mob reckon theirs are better but it seems that they are a con. The Chinese will sell u a big bag full of these. Some say they rust and damage the casing.

In theory the ceramic beads are the go. But how do u get them here for a sane price?

I ordered my beads when I ordered my first tyre off of Jake. Enough for two tyre changes on each wheel. Makes the post a lot cheaper that way.

As luck would have it, it's time to replace my rear tyre.

The one coming off has had the beads from day one and has done 9870 kms to the wear limits on the centre tread. It's not the best I've had out of a rear tyre but it's 1100 kms better than the last rear.

Perhaps I can say that the beads have had some benefit but how much is not certain. The old rear shock may have had some effect on tyre wear as well and any major difference  in tyre wear with the new shock might show up when the next tyre is due.

There are enough beads for another rear so they'll be going in this one as well.
