TPMS registers 2 psi low

FYI. Both F/R TPMS register 2 psi low on 2019 K16B. I own 2 high end digital air gauges that both read to the .1 psi of ea other. (Griots garage and Summit racing). I have noticed that both consistently measure 2psi low. Anyone else notice this?

only ever indicative, if that's what your bike reports stick to that. Possible that BMW could apply correction factors to the software

I only use mine as a warning indicator to a leak or other issue - I do not rely on them to be as accurate as my digital gages.

My 18 B was pretty accurate until i changed tires. Now my back is pretty accurate but my front is 2lbs. Off. My dealer says it's within margin of error.

In my opinion, the bikes air pressure readout is to catch a leak or puncture. I leave the readout on all the time so I'll hopefully catch a leak early should it happen.

Sudden deflation should take priority over other displays. Though it is my preferred display option.

I have never had a motorcycle TPMS be 100% accurate. Their job (IMO) is to warn of rapid (over the course of the day) or sudden (puncture) air loss. Mine served its purpose well, with the red triangle warning when I picked up a drywall screw on the slab in the middle of the NV desert (on an Iron Butt ride).

Took less than a minute to lose ALL air pressure, but I was pulled over before it was all gone.

FYI, my current TPMS on my '13 GTL is one pound low.

According to the MY2019 manual they compensate for temperature, with the reference point being at 20 degrees Centigrade.

This is also my understanding, that the TPMS software is always compensating for temperature variances. It was explained to me that the readout is always displayed at pressure adjusted for 68F (ie: 20C). This would explain some or all of the delta between display and gauge.
