Hi SamHanks
Thanks for the additional details. That's a bit strange, with the nature of BMW, I would suspect that if these pressure changes are allowed to deviate from spec (and that's rare), they would be able to do it with the dealer tool. From what we've found previously, only on oil cooled bikes though, the thresholds are available, but not on the LC bikes from what we've seen.
Were the tyres purchased from a BMW dealer or from a 3rd party?
Regarding the readout of 74 PSI, was this readout done while the bike is stationary? If so, it's most likely a default value that the sensor provides prior to activation - you can test this with the bike on the center stand, put it in gear and let the rear tyre roll for a few seconds until the sensor is woken up. Now run the real-time values and check whether the rear tyre value now reflects correctly?
I do work at HEX, so we naturally support our own forum :-)
To help us out with lifting the veils of mystery that appear, could you give me some feedback on what exactly is not known to you or people you've spoken to?
Kind regards
Ruan
