Tire balancing question

[SebasSF]

I picked up a 19.6x6 rim and tire to use as a spare, and took it to a local tire shop. They got it installed, but we're not able to balance it. One guy said you put a small bag of sand inside? Should I take it to a truck tire shop and get it balanced?

Sand balancing is what was in the aluminum wheels on my motorhomr when I replaced tires.
I was told that each tire should have certain amount of sand, not just an inderterminate amount. I purchased Centramatic's instead.
Good Luck, Derek

Are you sure it was sand or something like Dyna Beads? Tire Balancing Products

Sand has sharp edges and is abrasive. I don't think that would be good for the rim or tire. By the way I use Dyna Beads when I mount my tires.

Ok, so I took eh tire to a truck shop, and they used a bag of balancing material. Did not catch the brand. Thanks for the help.

The best way to balance a tire is with a road force balancing machine ,most balance the tire wheel assembly in the air with no load on it,this is ok most of the time ,but do you drive down the road with your wheels not touching the ground! The best way is to balance the tire wheel assembly is with a load on it ( real world condition) this is done by a special wheel balancer called road force balancer it applies a load on the wheel and tire by a roller equal to a load on the road , the reason road force balancing is better is under load a tire changes deflection and when the tire is manufactured some areas of the tire stretch more then others under load so you end up with a oval wheel under load to optimize this the road force balancer will measure this out of round and try and offset the out of round with the rim ( because all rims are not perfectly round) to minimize the vibration then a minimum amount of weight can be installed as a patch inside the tire or outside traditional weight .
