I just mounted a new set of 37" Swampers and was worried I wouldn't get them to balance. I remember seeing something on this forum about the Dynabeads so I ordered 5 bags of the larger ones that you just lay inside when mounting. They are very easy to install,balance better than lead weights,and you don't have to worry about knocking any of the weights off when wheelin. They are awesome and I will use them to balance everything in the future.
