Hi,
Following advice on the Rennlist 991 Forum, I have reduced my tyre pressures to part load/comfort pressures.
Seems to me that the pressures in my rear tyres (in my RWD rear-engined 911) should be higher than those in the fronts, but the electronic manual seems to have got them the wrong way round. (RA = rear axle and FA = front axle).
Certainly for ‘normal’ (non-comfort) pressures, the rears are all higher than the fronts in the Good To Know manual.
Error in Good To Know Electronic Manual?

Agree VanB.
Porsche has got their RAs and FAs transposed in the EM. Must be worth an Easter Egg reward if you alert them Simon.

Rears are a lot wider though which might offset the greater weight?
Tyres slipping on the rim used to be an issue and braking loads will be higher on the front.
Not totally clear cut.

^^^ It's an error Tim. The pressure on the label on my 911's B pillar state the lower pressure on the front, as does the paper manual.

Yep. Now running 29 psi (fronts) and 31 psi (rears) as per part load/comfort setting.
Lovely jubbley!
