Default Wheels for my Pentastar Ram 295/60/20? Maybe? 305/55/20?

So Ive spent a week searching forums until 2-3am, so dont tell me to use google. I get it... With that being said

I have a 2013 dodge ram 3.6L 1500 crewcab. I need tires ASAP and it was time to upgrade yesterday. I plan on buying bilstein 5100 set to max but Im waiting on purchasing my wheels/tires. My truck is a daily driver and will probably never see mud or any off roading. I love mt's but think its smarter for me to stick with at tires. The rims Im planning on going with are either 20x9 or 20x10 with a -12 offset... subject to change. I did buy the rivet style fender flares which a body shop will be installing for me.

Originally I was planning on doing 33x12.5 20 mud tires. But after research I switched that to 305/55/20 nitto terras. I like them, but I dont love them.

Further research showed me people are losing 1.5-2mpg with the 255/60/20s.. which isnt bad, so i started leaning towards that, but I dont have the hemi.





My question:

How much more mpg roughly would I lose with the 295/60 vs 305/55 on a 3.6l? If you dont own a pentastar, a guess would work because I have absolutely no clue.


Secondly:
Will that set up even work? Anyone have it? Ive been seeing yays and nays.

thanks in advance!



My History BTW:

I sold my 2007 tundra on 35 mt's because I was driving 50 miles a day and was getting 8-9mpgs. I LOVED LOVED LOVED MY TUNDRA, and it was cool and all while it lasted, but got kinda of silly real fast. I saw the v6 ram and was all over it. Pics of my last truck so you kind of get the style I am into. I miss that truck everyday:

Well first off you're looking at 2 completely different tire sizes. A 295/60/20 is 33.9"x11.6" and a 305/55/20 is 33.2"x12.0". So you're essentially looking at a 33" tire VS a 34" tire. Obviously the MPG loss with either of those tires is going to be different because of the size, weight, and rolling resistance difference.

Losing 1-2 MPG is typical but it depends on more than just the tire size. Driving style/habits are going to play into it. But you can generally expect to be in that range when going to a ~34" AT tire.

If you want your tires to be anywhere close to the outside of your flares you'll need a 20x10 -12 offset but with the tire sizes you're talking about you still won't be flush. Just a heads up on that...
There are a number of guys running very similar setups as what you're looking at and if you haven't found the Guide to Leveling that's linked in my signature yet you haven't done a very good job searching There's some links in there to different wheel/tire combinations so you can see how it looks.
Your major downfall is going to be the fact that you only have the 3.7L. You're going to notice the "power loss" more since it doesn't have much torque to get those tires turning.
