Other types of air-down tools are those that are installed permanently into the wheel. Advanced Air Systems, the makers of the Powertank CO2 tanks, offers the Monster Deflator Valves that thread into a larger hole than the standard valve stem. This 716-inch hole must be drilled and tapped into your wheels and it is suggested to do it opposite the stock valve. Once the 14-18 pipe thread hole is ready and the new valve is in place, you can simply unscrew the red locking ring and it opens up four 18-inch holes to allow quick airing down.
