5mph maybe but at low speeds ballacing isn't a concern, but once you get moving over 10moh the BB's are easily affected by centrifugal force to the outside of the tire, where they fill in as needed. Heck they are great for offroad tires especially, if you lose a large lug, that weight is compensated for directly next time your at speed.

I would disagree on the "45mph" cut off, anything to support that? It's simple really, if a powder works why wouldn't BB's?

well the BB's idea is sounding better just because Beakie made a good point that the BB's would be a lot easier to mess with and if i ever needed to change rubber it would be a lot easier to mess with the BB's instead of the powder but does like 8 oz of BB's sound good for like 35/12.50/15?? i have bigger ones but these arent balanced either and im guessing the smaller ones will be easier to balance than 38's??

have a look at this video for those who want to see/understand the theory behind the BB's

you can get dynabeads designed exactly for this purpose, but you can also use simple Airsoft BB's (just ensure you get the quality ones, not the cheap plastic ones you can feel the seam on)
here is a thread from a 4x4 site that explains a bit about how to calculate your weight requirements. a simple way, would be to have someone ballance a tire, determine how much weight is needed, say 6oz, then simply add that amount in BB's.
taking into account each tire maybe different, you can add 2oz to each tire, so they all get 8oz for example.
the one other problem you'll find with powders, is if you air up/down often for offroad use, that adds moisture to the tire, which affects the powders and causes them to degrade, or clump.
hope some of the helps, best of luck.

thats a good idea i think i will have my local shop spin the tires first and get an idea on how much weight i need then i will add BB's from there thanks Beakie!
that was a great thread on that 4x4 forum too.

used that on one of my old trucks and the balance was fine till you got to 70 mph and all the beads stuck in one place in the tire and started shaking like hell. the tires rode better unbalanced than with the compound.
working in a tire shop and using a road force machine for the past 10 years i havent seen a tire that couldnt be balanced that wasnt defective with that machine

I have the powder bags in my tires, went to carquest and picked up 4 10 oz bags threw one in each and we're good to go. And they definitely balance out waay before 45
