Balanced My Tires - Finally, and I found the trick here! Options

[76-914]

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.

kwales, IMHO you are making an apples to oranges comparison. Certainly we should have some guys on here who are physics majors or at least know about 1000% more than I do (which isn't too hard BTW) (IMG:style_emoticons/default/huh.gif)

Here's the only factor you seem to be missing in your lateral movement argument and comparing it to people on a plane; How much gravity through centrifugal force is being placed on the balls to basically keep them in a given relative position that would resist the less than 1G of lateral force in a corner??

You seem to be under the assumption that the balls are constantly in major movement in the tire. That is just not true. They fling out @ around 10mph and get fairly evenly distributed. When the wheel tries to bounce up, they momentarily move down on the fore and aft of the tire slightly countering that movement of the wheel. This happens constantly. These little balls have a tremendous amount of G-force holding them to the tire (this is where the physics guys who can calculate this come in). A .20 gram ball in a circumference spinning at approx 1K rpms @ 60mph =??? G-force on that ball?? Most folks are aware that a connecting rod at rest weighs around 1.5 pounds depending on the type of rod used. Spin that rod 3K rpms on a crank and it acts with the force of hundreds of pounds of force due to the amount of G-force placed on it.

When you turn into a corner, most folks cars can't muster barely 1G of lateral force on a .2 gram ball that may have the force of 10 - 20Gs or more on it. I don't know if the spinning Gs would effect and multiply the lateral Gs, I'll differ to those with bigger brains than I (IMG:style_emoticons/default/wacko.gif)

Another factor is the gyro effect that will counter any force that is not in line with the spinning of the tire.

Now, back to that plane. You put a plane in a 4-5G loop and no one will be moving from their seat, this I can assure you from experience. You end up right back at the gyro thing where its darned hard to counter gravity and circular motion.

Again, I will differ to those that have bigger brains with this stuff for the specific science of it. All I know is that it works and works really, really well.
