This is something I am looking into at he moment, as I am after wheels for ours..
You need to check pitch, some are 139mm, and others 139.7mm. over that distance, I am not sure how critical that could be though.
Also the centre hole is an issue in some of the other jap cars, no where near big enough.
The Terrano is
6 hole 139.7 pitch 100mm hole.
Then you need to know the
wheel size, 15, 16 or 17 inch.
wheel width, 7J, or 7 inches
and the offset, which is proving a bit harder to get a definitive measurement on
Basically between 0 and 35mm depending on where you look. The bit that seems to hardest of all, is not everyone lists if it is positive, or negative offset, just giving the distance. Makeitfit told me is Negative on the Terrano.
