Hello together

My name is Marco
I‘m coming from Switzerland.
I‘m here to clear some questions about forscan.
I‘ve tried to change the tyresize with it, but it came en error (P1635).
Original tyresize 265/65 R17
New Size 285/70 R17
I get the HEX for it but it doesnt work

Can somebody helb me?

Because the change you made is over the threshold.

Provide more information including what change you made or all we can do is guess.
