what PSI do you inflate your tires to

[Dangerous Fish]

Something's not right if you think 42psi cold is under inflated. What tyres are they?

You're measuring tread depth at the edges using these grooves each side (as opposed to the sipes on the very edges)?

It was measured by Tesla.

Oh dear... I suggest you check it yourself or maybe post a photo of the full width of one of your tyres so we can see the state of them.
I'm assuming you also haven't compared the car's TPMS numbers against an accurate gauge? You need to do that as well.

The cars TPMS value always matches my air pump to within 1 psi. I guess I could measure the depth myself….

It's an idea...

Ok I checked. Teslas measurements were correct, tires are definitely wearing faster on the outside, all 4 wheels evenly.

Upped the pressure to 45, definitely more firm ride now let’s see if it makes a difference in 10km, I’ll be doing a lot of driving next few months.

You said "on the edges" not "on the outside". When did you last have an alignment check?
Show us a photo of the tyre treads.

If you're at 42 now that's an alignment issue not pressures.

Absolutely right. At 42 PSI the edges on my MYLR dont even show any wear!

There's just no way 42 psi could be considered under-inflated. There's another explanation but without some more info it's impossible to say what.

Poor explanation on my behalf, however I posted the tread depths. the outer tread is wearing faster than the inner. Not the"edges".
No issues with alignment, balance just done and I'm at 45psi now, so will see if it makes a difference. Will try and get a pic later.

I have done 35k on these tires and still at 3.5mm so it isn't bad, hoping to stretch them to 50k.
