After searching the big 3 F150 forums and crawling Wheel & Tire threads, I noticed there isn't a Sticky for Wheels, Tires & Lift specifically for 2015+ F150s.

I was wondering if 33x12.50R18s would fit stock (18" 6-Spoke Machined Aluminum w/ Magnetic-Painted Pockets) wheels without a lift/level kit?

or

Will I need wheel spacers to run 35x12.50s on stock 18s with the Rancho quickLift or Fox 2.0?

I'm considering BFG KO2s or Pro Comp Xtreme MMT2 to beef up the look, but make no mistake, this truck will see minimal off-roading (rock filled parking lot to the trail, grass field, etc.)
