Message on TPM this afternoon. It suggested i needed 0.3 Bar put into a rear. It was only then I see there are lots of sub menus and settings. The standard display showed 2.1 on the rears. I stabbed a few options, selected 21 rims, limped to a Service Station, put 2.2 in each of the rears. They were about 2.1. Went on my way. It said measuring for quite a few minutes and then all the lights went out.
I still don't know what the correct pressure should be.

2.3 front and 2.5 rear is a good starting point.....😉

No time for that sort of thing.
It seems I have been under inflated since day 1.
Cold I have been 2 & 2.1. Driving will raise it by .1 all round.

As Paul says that is correct in the 20”
Had similar warning and put more air in and all perfect.

Without checking, I think they’re all the same - sticker on driver’s B pillar normally.

Probably. With all sorts of tyre size and load combinations. As the pressures have not changed since the start and seemed balanced i hadnt bothered to check further.
Thanks.

At least I can expand that and don't have to peer with my glasses on/off. I am reading that as 2.3/2.5 partial load.
