thats because you're shouldn't add air to a " hot " tireMax pressure is 41 cold rear, 36 cold front. Cant find any info on max pressure when hot.
I added the TPMS because it gives me actual pressure. The one that came on the bike just warns you when pressure is getting low.
If you want to use the factory TPMS you need to reprogram the receiver on the bike to recognize the different sensor in the 12 rim--the bike only recognizes the 2 sensors it came with until you tell it otherwise. Read this:I have the 09 with tpms-I bought a 012 rim w/tpms is there anything I have to do to have it mate with front tms as far as tire pressure? thanks in advance....rjw
