Just put the 80 spoke tubeless American Wire Wheel on my 2007 Ultra. When I got home they went flat. Found the Valve stem leaking at the base of the stem. Has anyone had this problem? The dealer said this is a problem with these tubeless wheels. Called American wire wheel and they siad they have not seen this proboem. Would like to know if anyone else has seen this and what they did to prevent it from happing again. Thanks !!
