Spare tire addition.

as I look back, it has been a while since I've had a flat.

Well I would not be driving on the spare except to get to a tire shop. If my math is right a 225-65 is about a 1/2” shorter than my 245-65’s. I could bump up to a 225-70 17, assuming one exist, and that is only .08” shorter than my 245-65’s. That brings me back to will it fit? I guess I could put one of my tires in there and see what it looks like. (Width would be an issue, but At least I would have an idea) All this crap could be avoided if Ford would just put the damn spare in there from the get go. Also, I read (on this forum) that the Bronco doesn’t have a traditional transfer case.

Yes, in “normal, eco, sport” modes the Sport is “intelligent” awd. The other modes are what “lock” up the various drive components (depending on your trim) and provide the quasi-transfer case.

As to the tire issue, 225/65’s are @ 1” shorter than 245/65”s, 235/65’s are @ 1/2” shorter. The Ford “full size spare” on my BS BL w/OEM optional AT tires (235/65r17) was a 225/65 (NOT a matching tire). It was close enough for limited use to get back to “civilization”. The 235/65 tire would “just fit” into the spare wheel well with all the padding in place.

When I put on 235/70r17 tires (30” tall) I decided the 225/65 might cause an issue, so I decided to keep the 1/2” size difference and put in a 245/65 spare (29.5” tall). It fits (with some effort) after all the padding is removed and you keep it deflated to @15/20psi. This isn’t a problem as I carry a compressor so I can pump it up after it’s on the car if I need to use it (hopefully never).

While rotating my tires on my 2023 Big Bend Bronco Sport, checked to see if the full size tire would fit in the well where the donut sits. It does fit but is a litte higher , however the floor mat will sit on it with it sliding into the higher groves in the floor.

The "full-size" spare is 225/65R17. As far as the proper foam, try finding a Badlands at a wrecking yard, that is the only trim that has always included a spare for its entire run (AFAIK).

imo, the foam serves no purpose. The slots cut into it for storage are too small to hold anything meaningful. I pulled the foam out and now have plenty of storage for useful items (battery booster, first aid kit, k-rope and soft shackles, battery powered tire inflator). The metal well and the retainer bolt/nut keeps the tire in place.
