Does this sound right and can you get these rims?
I like the US wheel 5 spoke or their rock crawler if you have them.

The details:

Nissan Xterra
Stock: 15x7
Offset 40mm
Backspacing 5.07
6 on 5.5

I am trying to find a 15x8, 4.5" offset rim...any ideas? This will kick the tires out a bit from the lower a-arms but not so far as to stress the front end components and should allow me to fully stuff the rear wheels. I can get them custom made but has anyone seen this backspacing before in a off the shelf wheel?

Well first of all most wheel manufacurers do not deal in "back spacing" measurments they use offset. The 4.5" measurement that you stated is a back spacing. Offset is easy to understand

As fas as the exact wheel that you are considering I would suggest that you contact a company like Summit Racing as they may have exactly what you are looking to get for your Xterra.
