I fit a 35 under mine no problem. Looks like there might even be room for up to a 37.

Did you keep the 18" spare rim or go with something larger? I've got 35s on my truck and definitely don't want to get stuck having to use the factory spare. Only problem is my brakes require a 20" wheel so really hoping there are no issues going with a larger rim up there.

I'm running 20x9 +0 B1 Fangs in Royal Bronze. Fits up there just fine on a 35.

It's tight in the back, but there's a few inches in the front so there is room to go bigger if you're comfortable having it that close to the exhaust.

your tremor configuration is different than standard F150. not sure if the tire will fit on a standard one

edit: it did fit my standard F150. put a 35" spare below and it fits.
