i wouldnt recommend doing that. i have a set of those tires cut, and while they work well for straight line, they dont provide enough sideways bite to keep them from washing out.
bad thing about the kenda tires is that the lugs are pretty stiff. i dont like them for normal riding, but cutting them works well for straight line dragging and hillclimbing.
what PSI do you run them at? 3 or 4 would be best im sure.
you would be better off running a different set of tires than cutting those for all around riding.
