I am not sure if this has been covered…or maybe not….??? But the TPMS on the GL1800…at what pressure does it come on to show your tires are low….? Asked the guys at my local Honda shop when I was getting some new tires…METZ 880’s front and rear. I asked them…and they could not tell me, I have looked in the owners manual to see if there was something on it, but could not find anything saying at what pressure it comes on to give a low tire warning. Any one know what PSI will it come on at…?
