From all the research I've done, it seens 35x11.5 is the biggest you can go with a 2 inch leveling kit without trimming anything. I opted for 285/65r20s since they are about 8lbs lighter per tire than the 35x11.5s... truck isnt in yet, but I have everything waiting.

I'm running LT285/65r20's on factory FX4 rims. They work out to be about the same size as a 35x11.5.

The 5.0L and 3.55 gears is ok. But a 4.10 gear would help with the get up and go and gass milage.

It would take several years (10+) to make up the cost installing 4.10 gears IF you did actually save/use less gas
and yes, you can easily run 285/65/20's

Can I run 285/65/18 on stock rims and no lift in 2017 XLT 5.0?

True, but than I thought it needed 3.73's when I bought the truck new. I did notice a sizable difference in performance when I went to the bigger tire. It accelerates slower, (noticeable) down shifts earlier on hill, and I get around 60 fewer miles around town on a tank (36 gal) of gas. But after driving it a couple years on the tires, I still haven't decided to go for a gear change or not. If I keep it, and don't trade it in this fall I'll probably go for the 4.10 gears and upgrade the interior to leather. If I trade it in, I'll probably just order a new truck with 4.10's from the factory and put these wheels and tires on it.

295/60R20 seems to be the most common size I've seen on leveled trucks
