Nissan Pickup Wheels

Hi all, new to the board ;)

I have a '97 Nissan Pickup and want to put the largest BFGoodrich tires possible. What's the biggest size I can fit w/o any rubbing?

Thanks,
Shane

If this is the standard 4X4, the largest is the 31X10.50-15 without a lift and that needs at least 7" wide wheels.
