Is the factory spare okay with the bigger tires if you ever need it or would a larger spare be required as well? Aren't AWD vehicles fussy about tire size? I have even heard never just change one tire on an AWD because the difference in tread height can f-up an AWD system. I know when I had old Ram 4X4, the spare tire had to be the same size (height wise) otherwise you could really f-up the 4WD system.

Seems Ford was okay with @ 1/2” difference in diameter between spare and other tires. The “full size“ spare was 225/65R17 (28.5”) on the BL and the optional tires were 235/65R17 (29.0”). If you put 245/65R17’s (29.5”) on the ground you should be fine with 235/65R17 as a spare, and it will fit in the spare well (at least on pre-2025’s).

I believe that the factory spare will be fine. If needed, it would be on for as short a time as possible. Thanks for the thoughts.
