I would like to add this. The stated tire pressures are with cold tires. So in summertime (around +20 C), the tires will move up +0.2 Bar after just a few km of driving at 70km/h. When it gets below 0 C outside I need to add 0.2 Bar to maintain the cold tire setting of 2.6/2.4 Bar and it gets to 2.8/2.6 Bar after about 10-15km of driving (high-way speed).
So in short, with rather slow driving an increase of 0.2 Bar when filling up the tires is necessary to maintain the suggested tire pressures.
I run at 40 front 35 rear because I was getting wear on the outside of the front tyres and to hopefully improve efficiency. Only negative is that on occasions I can feel the extra hardness in the ride.
I run 40psi front, 36psi rear on my 135 GT line. I think that lower pressures induce tyre wear on the shoulders of the tyre and putting a bit more air in evens up the wear across the face of the tyre. I haven't noticed any loss of grip or comfort with the increased pressure.

Tire pressures on a Zoe is a joke.
On the 2019 ZE40 R110, it is stated 2.4 Bar (34.8 PSI) on all 4 wheels.
On the 2020 ZE50 R135 running on the same tire size 195/55/R16 it is 2.6 in front and 2.4 Bar in the rear (37.7 PSI front and 34.8 PSI rear).
From a tire and weight point, they are identical.
I have raised the issue with Renault technical support.
Their answer was "talk to a tire shop" we do not know...
