FOR AIRLESS TIRES ONLY - The Tannus P-Tool installation pliers make installing Tannus tires a literal snap! Simply position the P-Tool’s tooth over the locking pin and snap it into place.  This tool is not required, but makes installing Tannus tires easier.  All Tannus tires come with a stick tool, but the P – Tool allows you to apply more force with less effort and helps when the tire is a tight fit for your rim.
