basically it's wrapping 60lb (or higher) braided fishing line around the smooth part of the tires to create " belts" on the outside. this will keep the tire from ballooning. i used 4 rows on the flux tires and 4 on my buggy tires. after you wrap the fishing line around the tires (i do each row 4 times) i tie it off and then put a couple of drops of CA glue on the knot so they won't come untied. it works very very well.
here's a few pics:
hope that helps.
