I had occassion to fit a 31" spare on the rear when all others were 33" (just how things happen some times....)
I have ABS!
On a long sweeping curve that I wanted to slow down on, the brakes felt rock solid but the ABS was working overtime and the car was only being stopped at a minimal rate - The ABS thought I was on ice or something and wouldn't allow the brakes to work too hard. Needless to say when I did manage to stop (about 300m) I pulled the ABS fuse out. I managed to get home without further drama (or damage to gearbox, Transfer Case or diffs).
I'm just grateful that I didn't find this out while trying to pull up at a set of traffic lights or something.
