Bar to psi setting ?

[Kithmo]

Noticed today that on the TPMS screen in the 5, the pressures are in bars and I can't find a setting in the car or settings menus to change it to psi, is there an option somewhere ?

There is no setting. We just have to get used to Bar.

No you can set to PSI in the car settings.

No you can set to PSI in the car settings.

On the MG5? It's not the same as the ZS. You can select miles or km, but nothing else.

There is probably something hidden away and changeable via OBDII if you know what to set. The problem is finding out how to do that without bricking your car.

I tweaked a few things that way on my last car (a Mondeo) - adding proper tyre pressure values rather than just a low pressure warning, getting a digital speedo on the right of the dash etc.

2.2 bar = 32psi
2.27=33
2.34 = 34
2.4=35

Probably not worth trying to change the display inside the car...?

I used the Carista app on the Prius to change some stuff that was "dealer only" changeable.
The only trouble is that most these apps don't have newer car settings on yet.

I was thinking of upping the pressures by about 3 psi, so it looks like 2.4 bar should do it.
Is the monitoring system self learning after changing the pressures like on the ZS ?

I'm not sure what's self learning about it; it reports the current pressure.

I've gone for 36psi so 2.4-2.5 bar. The ride is slightly less forgiving but it should help economy at 70mph.

Learning what the new normal pressures are and when to warn you the pressures are low.
Does it just warn below a certain pressure or is it a percentage loss like my Prius was ?

 

[Petriix]

I'll let you know if I ever get a warning, but that's unlikely to ever happen because I check reasonably often.

36psi seems high. What is the recommended pressure?

I cannot speak for the MG5 as a ZS owner but the ZS recommended settings are 33PSI for one driver but if the car is fully loaded is 42PSI and these figures are when the tyres are cold.
I run with mine at 37.7PSI when warm which is about 35.5 PSI when cold.

My readout changed from psi to bar, all by itself...hey ho...

 

[greentangerine]

MG5 is 2.2 bar front and rear, regardless of load.

To be honest, I set them high in advance of a long, fast journey to improve efficiency and didn't feel like lowering them again afterwards. They give you a bit more feel for the road through the steering wheel at the expense of a slightly harsher ride which, overall, I prefer. I'll keep an eye on the tyrewear but I tend to wear the shoulders more anyway. The only other concern would be driving in low grip (ice or snow) which would prompt me to reduce the pressure again.
