I have a 2012 Goldwing with a Hannigan Reverse trike kit added, the wheels Hannigan supplies are American Racing wheels and the valve stems come out at an angle (I do not believe 90 degree angle stems will fit). I would like to install TPMS on my trike and would like to know if all metal valve stems are the same, diameter wise. Currently I have a pair of aluminum threaded straight stems and would like to know if they can be used. I would rather not have to dismount the tire and pull the rubber valve stem to find that the aluminum ones I have do not fit. Thanks in advance
