Hey Nemo!

Hope everything is going well.

Check out the 2gnt wheel database for size/offset and pictures in the Int/Ext section.

I am partial to 16's with the fat tires, but 17's look great. I personally would go with 17's only because you still have a good amount of tire around the wheel.

As far as offset, I think that +35 or +38 looks great and fills out the wheel well.
