Only time I 'feel' a difference to conventional balancing is when going through a particular double S bend on a country road at cursing speed (50 - 60mph ish), there is a VERY slight shimmer for the briefest of moments where I think "oh a wobble" and then its gone. I think the forces in that bend make the BB's shift slightly as they find the where the need to go. With that in mind I presume there are other road conditions which would cause that so would be wary of using beads/BB's in a fast road car......but in landrover... whoopie they are a great solution. Tyres remain balanced as they wear or loose chunks of rubber off road. No lead weights to tear off. They greatly help counter against that wobble you get when mud sticks to the inside of the rim. You can fit and balance the tyres yourself as and when you want without having to visit and pay the MAN.
Have driven all UK roads types now with 8z of airsoft BB's in each tyre and the ride is smooth and without shimmer throughout the speed range of my truck on greenway anaconda's.

Could you not use the BB pellets used in softguns... these are a lot cheaper??

I dunno how much they are selling for but I expect it would be cheaper to buy direct from USA.

And no, I don't think gun pellets would work, they are too soft, a lot is made of the ceramic qualities that they don't wear much and keep their shape, gun pellets would rub and create a lot of heat and possibly melt together inside the tyre I think.

I had to take a tyre off the rim recently and my airsoft BB's still report in A-OK. Other than turning dark grey/black (from the tyre wall rubber) they have yet to show any sign of deterioration in size or shape. No melting.
I will report back in a years time.
