285/70/18 or 295/70/18 with this setup?

I read through the thread from 5 years ago on this and I'm still torn. Wheels are coming in Monday. My heart is pretty much set on Toyo Open Country AT III.

This is what will be installed:

Icon Rebound 18x9 25mm offset, titanium in color
Eibach Pro Truck Lift Stage 2R
+2, or +3 CB shackles
SPC UCAs
New TPMS

I'm most likely gonna order TPMS from Clockspring Experts, unless someone can suggest better place, higher quality TPMS

SO now, should I go with 285, or 295?

285 are 6lbs lighter per tire, and just over 1/2" shorter (6/10" to be exact) MPG should be slightly better, yeah I know, you don't buy a Tundra to save on gas. I'm kinda leaning towards that route, but I've seen so many pix on here with 295 as well and like it. I will also be towing a camper from time to time.

This is how it sits today. I'm keeping the wheel/tire setup. They're Michelin 275/70/18
