what size are the stock tires on 2004 supercharged xterras? are theyy any good for mild to moderate offroading? would it look ok if the xterra was lifted 2 or 3 inches?

First off, welcome to the board.

Secondly. You need to start doing some searching. Tire sizes can be found here as well as www.nissan-usa.com There are also plenty of threads about lifts with pictures of the trucks that have them here.

Now Schlud, while you're handing out clues, you could at least have moved this to the tires/wheels section...

The stock BFG Rugged Trail tires are only decent off-road, and they're about 31" in diameter.

I thought I did. Well it's moved now.
