disagree. the material gets slung out of the way, and the tires will eat up the asphalt and kick it out leaving a ditch where the tire was asphalt is very weak and shitty material....its only used because its cheap to repair and resurface, and freeways and high traffic areas have concrete poured under the asphalt to give it strength http://www.youtube.com/watch?v=At4E6A1YMQQ watch that video - at the end you can see a small ditch where it dug down before he started to walk it in circles....and thats a crappy knob tire - a street bike will tear up asphalt a lot easier while some light burnouts will indeed just leave rubber on the road - if its a standing burnout and the asphalt heats up enough, it will begin to tear apart
