So I make no assumptions:
1) Kept the sensors and rims located in the same positions (and just replaced the tyres)?
2) You have gone to the Settings -> Vehicle Information -> Vehicle Functions -> Tyre Pressure and tried pressing Reset
It should say something like reset ok (then you need to drive for about 5-10m to have the TPMS alert disappear).
If not wait till tyres are cooler nearer ambient temps and try again

post screen shots of what you are seeing - you might have message saying cannot perform cold reset (can't remember the wording, forgot to take photo)
along with the Off-road -> temperature screen.
With your new tyres is the TPMS monitor responding to the sensors?
- You can go to Offroad -> Temperature and if you drive the car you should see the temps and pressures on the tyres update every few minutes (perhaps every one)
- Temps should rise a degree or two within the first few minutes of driving - this way you know the sensors are coded to the vecicle and the vehicle is talking to them.
- Have someone screen shot this whole you are driving, our stop a take a picture if there is change... and post
In an ideal world with a TPMS tool - you capture all wheels sensor codes upfront and check that they are back in the same positions afterwards
And with a TPMS tool (eg Autel TS508 or other Autel model or OBD2 test tool) you can trigger the sensors and see the results immediately on the Offroad -> Temperature console display of the vehicle (with the ignition on but you don't need the vehicle running).
