Well, after 3 trips back to the tire shop I have them balanced. You'll think this is nuts but try it. First let's give credit where it is due. I clicked on the link posted on aircooledtechguys signature and found this article on balancing tires with air ball bb's. $9 at Wally's and you have enough for 20 tires. It was listed under under "cheap tools" on his website. Basically you put 1.5 oz's in each tire and thats it. So the 3rd trip I took 4 bags weighed out at 1.5 ounces each with these plastic 6.5mm bb's and had the "tire dude" break the beads and insert the bb's. I got some funny looks but it seems to have worked. PS. These can't be used if you have a tire sealer additive in your tires, ever! He shows white balls in his article but I much preferred the competition red bb's.

Andy, Pilots do a weights and balance on the aircraft and place the cargo to balance the plane. Moving all the passengers to one side will upset the balance of the plane and steer it....

76-914, I still think the balls are going to go wherever they want because they are free to roll. I think they will move to the sidewall during a turn, and that the pavement dividers are going to excite the free rolling devils so they run amuck.

Take the balls, put them in a cookie pan and tip the pan so they roll. Blow on the balls to simulate side loads from cornering, and they will move to the side wall of the pan while simultaneously rolling downhill.

Tap on the bottom of the pan as they roll downhill to simulate the impoact from the curb dividers. (thump, thump, thump) Bet that some bounce up off the pan, they don't roll as smooth or in the same pattern as unexcited, and that means your wheel balance changes for every curb divider hit at speed.

Done enough vibrational testing and excitation to really doubt this, but I've been surprised before. It meets one of the classical rules for a science puzzle- a sealed box, and you can't view inside- aka Schroedingers cat. Is the cat dead or alive?

Still want the camera shots.

And how does that related to them little balls?

You're still comparing airplanes to ceramic balls.

Every time you mentioned your plane it was always just moving passengers around in the plane.
To even come close to be comparable, you would have to let the passengers be moved by the planes cornering forces, not them running around on their own.
Your comparison just doesn't hold up at all ...

The whole point of the balls IS the fact that they move around. If they were static, they would be just like any other wheel weight.
You're still trying to compare them to static scenarios, which just doesn't work.

But hey, you are the "engineer", so what do i know ...

PS: And while we're at it, you got the Schrödingers cat analogy wrong too. Of course you can open the box. In fact, the whole point of his experiment was to open the box. In more scientific terms, a observer (any observer!) changes the outcome of the experiment because observing always involves interaction with the observed ...
