As I mentioned before, the TECH balancing compound originally was made for commercial trucks.
Now they have made the same for pass. cars / light trucks.

Emne: Re: [FWDLK] More on Wheel balancing
> Hello All,
> Has anyone pointed out the obvious? I live in Ohio, with what have to be the worst roads in the US. The surface of before stated roads shakes the mirrors of all (4) of my cars at speed. The rain grooves and pot holes do a real number on wheels/tires in this part of the world. Also, my Chargers always had a vibration at speed, until I had the DRIVESHAFT balanced. This took care of the most of the vibes. He could just have a driveshaft out of balance and causing the problem.
> Finally, I used to work with a commercial truck tire supplier. They had the techs that would change the tires on the side of the road when a semi looses a tire. Those tires were balance with ball bearings that were placed into the tire before it was inflated. I think ball bearings would be too big for a car tire, but you could try lead shot funnelled into the valve stem once the core is removed. Not sure of the quantity needed though, as I think the techs had some way of determining. Either that, or they just dropped a few in and hoped for the best!
