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.

Do a force vector diagram on the balls when cornering.
I bet they move sideways. Centripetal force produces an effect similar to gravity. In the old science fiction movies with the rotating wheel space stations to simulate gravity, the astronauts can walk around without being rooted to one spot. And if the astronaut is pushed sideways towards the sidewall, he moves in the direction imposed by the push. Same with the balls in the tires. A side centripetal force can move them sideways while a rotational centripetal force holds them against the inside of the tire. Instant dynamic imbalance.... |

Instant dynamic imbalance.... Or maybe not ... Wouldn't a deforming tire (due to side-loads) negate any static (good old weights) balancing anyways? As soon as the sidewall starts to flex, any balancing done with conventional weights becomes completely useless ... (IMG:style_emoticons/default/shades.gif) Andy |
