355/65-18 Terra Grapplers; 37/13.50-18 Mud Grapplers

My new 18" wheels come in on Monday. The intended tires are 325/65-18 Nitto Terra Grapplers but on the Nitto web site they have 355/65-18 and also 37/13.50-18 mud tires.

Does anyone run either of these or the same size in another brand? Do they work without a lift?

I have the 325-65-18 Nittos on mine and they are fine. No rubbing, but they do stick out from the fender wells and ALWAYS find the water just after I washed the truck! You can kind of see it here.

I have 5.5 lift with the Nitto 38 x15.5 x18. Love the Mud Grappler, its loud with the window or top open otherwise I barely hear it. excellent traction and wear so far 20,000 miles, looks like anothe 10 - 15,000 left.

However there are a lot of people running 37 x 12.5 without rubbing. 13.5 width would probably rub when turning or flexing.
