Balancing tires with internal beads?

[Jonk67]

:wtf Came across this, would this really work? Might try it in my small trailer tires but wonder how effective it is for our car tires? Doesn't really make sense to me art

Ended up there after reading the DIY soda blaster article, will try that on the next part I need to wirewheel.

That is an interesting idea.

Re: Balancing tires with intenal beads?

It's been done on large tire, especially heavy equipment tires for years. I'd guess the BBs he uses would work well, that is basically what they use for large tires. I had heard they did not do well in high speed use <shrug>

From past experience in the tire business, it works well on heavy equipment most of the time. An issue with cars is low speed out of balance because the tire has to spin at a minimum speed for the beads to settle into the area that they are needed in. Trucks have used a like item with the beads in a circular tube that mounted behind the wheel....worked ok....but nothing beats a good balance with quality equipment. They were used by trucks that were in and out of copper mines in Az. because they would knock lugs off in the rocks and that screwed the balance.

-You start driving and at around 10-15mph, the beads are flung out by centrifugal force and are stuck to the inside of your tire.

- They roll around naturally distributing the weight evenly


Mmmm physics what it is doesn't change.....why would they, the group of beads sitting at the bottom of your tire, after being forced by centrifugal force then decide to naturally move about and distribute evenly or rather to the unbalanced part of the wheel?
Oh I agree that they will move but naturally seek and find the unbalanced part of the tire, I doubt it. Sure they will move about as would anything inside your tire going around at various RPMs.

And how many tire mounting places would take the chance that pouring beads inside what they mount wouldn't create a legal problem for them?

I wonder how awful all of those beads sound like when the tire stops spinning and the beads hit the center part of the wheel and then finally the bottom. *dingdingdingdingding* All one needs is a machine to light up like a pinball machine!

I just did this 2 weeks ago on a mud truck with 38" 14.5 15" TSL boggers, 6 Ply tires, and i put 6 ounces of BB's, 1. Chew can full (redneck i know) It works like a charm! before the BB's 45mph was top speed without crashing this weekend i was cruising at 65!
