Larger tires on 2022 Bronco sport

[Deathmiester]

I wanted bigger ties on my 2022 Bronco sport. I got Cooper discoverer road and trail, 245/60 R18s. They fit, look and function great. No lift or modifications. I've used Cooper discoverers for yeas. Great tires made in the USA.

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.

The donut spare I have is smaller than the other ones.

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.
