Tire drops down on the cut out and somewhat like a paddle, the next row of knobs gets a full, deep bite on the ground. Best launch I ever have got on grass & dirt. Leave on my banshee in second very much like in sand. I don't see why every other row of knobs cut wouldn't work similar on other types of rear tires if cut in a similar pattern.
These are mainly for straight line drags, you won't corner like on your x-drive bkt's, hole shots, razers ect.
