Re: Balancing wheels on the bike
 
I checked one on machine after doing it on axle stands and it was fine, you can get within couple of grams easily.

No difference between static and dynamic balance on those machines, just easier, they're not like a multi-plane balancer that you'd use on a crank or something.

Not for bike tyres anyway, but wide car alloys with low profile tyres can be a nightmare to balance. This was the only machine I could find that would balance the wheels on my Vectra SRI properly.

i just remove valve core pour in required amount of ceramic tungsten beads (dynabeads) replace core fill with air and away i go.

Interesting...never seen Dynabeads before.

i was sceptical about them but i have been using them since April and they work. no more ugly weights to get in the way of cleaning my wheels :-)

i calculate the weight required by multiplying .25g by the width of the tyre e.g. .25x160 = 40g

they are suposed to be re-usable if your a tight wad but for the price of them i just use fresh ones as i got a big bag of them, enough to do 2 fronts and 4 backs for about the same price as i was going to pay for the sticky lead weights.

Explanation on their website doesn't help much :confused:

Re: Balancing wheels on the bike
 
i'll sum it up.. as your tyre rotates the beads collect inside your tyre at the point your normal weights would be at. but as your tyre wears this point changes so external weights would be inaccurate where the beads will move to where they are required to balance the tyre. this makes the beads a constant dynamic balance. one thing to note is that they don't work at low speeds e.g. below 25mph but if your tyres need balancing at these speeds then there is something wrong elsewhere.

What's to make them collect at the light spot? I can't think of any physical reason.

That's a car wheel though, dynamic balancing (2 plane or more) lets you balance any "rocking" imbalance which static balance doesn't show.
