Tyre pressure issue

[Gaffer1]

I have had my model 3 for just over a month, I have done 850 miles and tyre pressure light has come on saying I am losing pressure in the drivers side rear tyre. Is this normal?

I am not sure what you mean by "normal"..... your first order of business is to inspect the tire (or tyre as you say over in that part of the world) and see if you picked up a nail or something.

Already done that, no nail detected

Then I suggest you check and fill all 4 tires to whatever the tire pressure specification is on the door jam for the tires that came with your car. Even though its an EV, as it relates to tires and such, its no different than any other vehicle, so you can do the same thing you would do with any other vehicle.

if it continues to lose pressure, all the same things that would impact that with any other vehicle would be in play... bad stem, something in tire, etc.
