I took my Hercules powered 715 for a highway ride this week and as soon as I reached around 45mph my front-end began to shimmy pretty bad. I am guessing I have an out-of-round rim. I have Denman 16" Radials on the truck.

I had a similar problem with a Humvee that I owned a few years back and I had Equal Balance Powder installed and it took care of the problem.

Has anyone else used this product to balance their tires?

Here is their website for reference...
