Interesting, I had upped the psi from the recommended 33/30 front/rear when I replaced the tyres because of my concerns, I’ve run about 36/32 psi from new but you are using around 40+psi and I dare say the recommended are around the same as mine at 32psi or 2.3 bar.
I see some more experimentation going on. Clearly my tyres are fine with higher pressure, I may try pushing toward 40psi front and see how that feels.
From observation aside from the wear the car is still wriggly on the tyres at this slightly higher pressure, if you give the car a good rock, the tyre seems to move way more freely than I would expect and this in my mind means the suspension isn’t as active and in tune as the tyres are more wobbly than oem. However expectation isn’t always the same as reality hence asking
