Tyre Pressure Monitoring - COLD pressures and agjustsments when HOT

[tw99]

You check tyre pressures before riding with a gauge of your choice. Set them to 2.5/2.9 then ride your bike and forget about it. The tpms will keep an eye on it for you, just forget about it until your next check with your gauge. No need to over-complicate it.

Is pretty much what I do too.

I'm fairly sure the TPMS on my 15 plate saved my skin a couple of years back.
We were heading back from a week in Scotland, and i was leading the group, travelling at about 80 heading from Tebay to Kirkby Stephen. There is a long straight which then rises up hill into a right hand curve which you can easily take at that speed. Just as i was reaching the tip in point for the curve, the dash started flashing red. Up to that point i had felt nothing wrong, probably due to the centrifugal forces keeping the tyre in shape, but going through a turn would be a different prospect. By the time i'd stopped, the back tyre was flat to the rim.

My two penneth.

I think some people do over-complicate the TPM system.

The objective for the system is safety, and it's meant to warn the rider about a drop in tirepressure, and the warning level is set at such a pressure level where the bike is still safe and controllable.

The built in temperature compensation is there in order to tell the difference between a real puncture vs fluctations caused by the tire being warmed up when riding active.

It's installed in the GS/GSA, which is not a racing bike, and the riderers are not Rossi.

To the very few gifted riders that are able to tell the variation of +/- 1 psi, the system is a waste of money. But to the majority of the fat tossers, like yours truly, it's a blessing that offers an early warning that helps us clearly not very gifted riders to handle a puncture in a safe manner.

Perfect summary imho

I know this slightly off topic, but the previous generations of TPMS I had on my 1200 LC & 1200 oil head were far better than the one I have on my 1250 - this one seems to vary too much, and like a previous contributor said - even the BMW techs cant really explain the new system

I had to put some air in when the tyres were warm. When I got the bike out on Sunday the tyre pressures had 2-.4psi difference, cold, to what they were when I added 4 psi when they were hot.

I’d say it matters not whether hot or cold, it’s within a gnats cock of a difference.
