I have developed a 50-55 shimy and have made several trips to RC, chunked both tires and rims and never had to re-balance my tires so I figured it was time. I dumped in 8 oz of competition grade airsoft pellets in my 35 12.5 15's and not the shake is even worse at 50-55! Do I need more beads? or maybe a few more ounces of antifreeze? I have heard these things are amazing for balancing big tires what gives?
