More then likely you'll be fine with the properly sized tires. What you'll want to make sure of is that the Pathfinder wheels don't have more backspacing than your stock wheels. That's highly unlikely as the stock wheels on the X have quite a bit of backspacing. But your biggest priority is going to be sure you don't rub against the suspension.
So Keep you backspacing about the same and your tire size appropriate for it and you'll be fine.
