Changing tire size effect BCM settings?

Changing from stock 20” to 22” anything I need to change with BCM for tire size or TPMS settings? Thanks in advance

I went the other way so dropped from a 20 to an 18 and then went up from stock tire size to a 35" tire and everything is happy still. The computer cares about overall tire height vs wheel size so if you end up with a lower profile tire on a bigger wheel that should be very similar anyways.

Wheel size doesn’t matter. Tire diameter is what matters.
