Now here is some logic for you (fun logic exercise):
If all MKIII & MKIV rims that have the same height (16 in this case) also have the same inside dimensions (meaning the inside wall opposite the traction side) than the following must be true:
1) This spare tire and wheel will fit on a N/A MKIV.
2) If TT MKIV's that come stock with 17" rims can take N/A rims (16"), than this spare from a MKIII will fit.
3) If MKIV TT's have 16" rims for spares, than this MKIII rim will work.
4) If all MKIV's have the same sized spare (assuming that spares would all be 16" because Toyota won't make the "universal" spare a 17 because spares are always smaller), than this will work.
Other things to consider:
MKIV's and MKIII's both have the same bolt pattern (so that is not an issue).
I have seen a MKIV with MKIII sawblades which would be 16x7 (but we can not know if the brakes were stock nor if it was a N/A or TT model).
I used to study tests like that.
So for once, I thought I'd write my own example.

The logic goes pretty well, except that the MKIV TT spare is actually 17". I believe this is so that, if run in the rear, the LSD doesn't behave strangely.

NB: Please consider posting any help requests in a new thread instead of asking me for help privately. About 99.9+% of the time, private help requests end up covering great information that could be very valuable to other forum members. If you have a good reason for needing the help request to be private, I'll consider it. If not, then why not give everyone else the opportunity to pitch in too, and/or learn from the information?
