I wonder do they have 'cold' values as the baseline then simply raise them by the same amount as tyres actual rise from cold to warm

Seems to fit from the shots above, doesn't it - often simple is easiest!

 

[Dashnine]

Yes as per the manual

It's a neat solution, I wonder what logic / algorithm they use to predict what the hot pressure will be.

 

[Dashnine]

Mine do the same.

It's perfectly normal and the pressures will return to normal once the tyre cools down.

Check the photos - his 'target', fixed pressure are changing too, presumably so people don't let air out of the tyres when hot to match the cold target pressures.

Must be a new trick with MY20 then.

I know the actual pressures change, my query is my advised pressures change slightly too ! I'll post pictures later

No, they don't. Only one set of figures change dynamically. The 'fixed' pressures only change if you change the load setting.

Is it correct that the advised pressures (the ones in brackets) changes. I've 20" wheels. Was telling me advised 37 front, and 35 rear. Mines were all a little low, so set them accordingly. Pulling out of the forecourt, I see advised were now 38 front,37 rear.

This morning when I check, there are back to 37 fron 35 rear. Do the advised settings change with temp ??

No, the dynamically changing pressures are the actual pressures, as the tyres heat up with use (pressure rises) and cool down when stationary (pressure drops).

Pumping up the tyres again as we're three up with luggage and with bikes on the tow bar. Still find it somewhat alarming that normal load setting is 50psi on the rear (40 on the front), which is the max inflation pressure for the Conti tyres.

Accepting there's a safety margin, and that the tyres gain a few psi when in use, but is it such a great idea to have the normal setting (the 'comfort' setting is 37/32) right at the max tyre pressure?

Have you actually had any warnings when running pressures which are not close to target settings ( high or low ones)? One of my tyres was several psi low on delivery but it didn't trigger any alert. I suspect the permissible range is a bit wider than it would be for an ordinary car given that off-roaders might want to drop tyre pressures to suit conditions. Perhaps warnings are only triggered if the is a sudden drop in pressure on one corner only.

Yes when setting the high pressures I set the load setting first and you get a warning diagram with the low pressure corners highlighted. As I remember the highlighting disappeared at about 3psi from the correct pressure. No warning of high pressure when resetting to low load however.
