I am opening up a new topic since the discussion of use of balancing beads
has wandered.
There appears to be many name brands including Equal, Counteract, etc.
I had used Equal brand on my 78 EL2 for about 20k miles. I bought some 4 oz.
packs online and took them to Wallyworld with me when I bought 2 new fronts
in size 245-75/16 in the summer of 2005. As I recall I paid about $6-8 per
bag.
The grunts at Wallyworld were very 'reluctant' to install the packs [also
since I declined the 'road hazard extra-cost package! ], stating they had
never done this before. Sounds like an ole time honeymooner!.
I persisted and they complied, and beads have been in since with no adverse
effect that I can detect.
I am now shopping for 6 new tires for my 76 Glenbrook and am preparing a
cheaper and simpler remedy.
I bought from Wallyworld an industrial size plastic jug of air gun pellets
in sporting good area..
They offer a selection of colors but only the black ones are 'super weight',
and slightly more pricey, like $10+ instead of $9 per jug.
I measured these out into small plastic baggies and as I recall, it yielded
a dozen or so baggies. Not a bad deal for more than enuf.
I surfed the net and came up with a lot of info on the touting of beads or
marbles or even golf balls as a balancing media.
It has been out there for a long time.
Herein are some of the many videos which show in vivid color just what is
happening.
The first one, with the hand drill demo, is particularly interesting and
anyone can do it to convince themselves.
There was one site which did some mumbo jumbo about static electricity
forces and having been a grunt scientist at Xerox involved in electrostatics
several careers ago, I ain't buying that one.
Seems it is just a simple balance of forces phenomena.
[Rob, doesn't even involve SCALAR vectors!]
And interestingly, ever time you stop, the beads fall to the bottom; and at
start up, you get a new, fresh dynamic balance; this will compensate for
wear and tire life. And unlike lead weights, the beads also give you wobble
balance, that is, side to side..

Chart denoting how much [by weight of beads] is required per tire size.
Seems like 4 oz. is right for our GMC's.

Should this chart be in our permanent reference files?
If one surfs, one can find many such demo sites, including installation
techniques; enuf to amuse for a while.
