not siping but making more "lugs" out of the stock pattern.

for not being a newbie anymore, that's a pretty newbie post.

The answer is simple: you buy a tire groover, and start cutting.

Lance even did a writeup and it has a link on the mainpage http://www.pirate4x4.com/productreviews/swamper-impact/index.html

there someone on this board that did it with a grinder once too.. even though he had my grooving iron at the time. I wouldnt recommend it, I heard it was a mess :D

wow, very good info.

Seen it done with a chainsaw once, wouldn't recommend it, but it did get some very good traction out of some old Military tires.
