Wanted to share that I was able to fit a Cooper AT3 Xlt 295/70/18 on a Rebel rim under my Laramie.
it was super tight and I ended up letting some air out to get it seated.
I didn't want to have to carry a spare in the bed so this worked out well.
It fits and doesn't look like it will hit the rear trackbar. Will put some miles on it to be sure.
These Cooper tires run small. Not sure a Wildpeak or other "truer" to size tire of the same size would fit under there.
You could modify the heat shields but the hitch and trackbar appear to be the limiting factors.
Hopefully this is helpful to someone else looking to get the largest spare underneath
