I was in a 4 Wheel Parts today briefly and saw some Super Swampers (TSL SXs I think) mounted on Weld Stone Crusher rims and out on display. I looked at the back of the rim and I was stunned at how many weights were used off to one side to balance it. They used both the square kind that mount to the inner face of the wheel (a bunch of them) and a bunch of the traditional kind that clip over the rim. Apparently this wasn't enough though, because they had also taken a file to the opposite side of the rim and filed a bunch off of the 90 degree radius where it becomes the inner circle of the wheel. WHOOO!!:eek:

 

I believe it. Those big bias-ply tires are damn near impossible to balance. Even the big radial tires can be difficult sometimes.

 

It took quite a bit more than I was used to seeing just to balance my BFG'S
