So the mod bug has bit.
below is how my truck sits. Lowered and tuned
I just got the urge to level it. Scored bilstein 5100 front and rear.

Problem is I drive 500 miles a week!

Trying to the of pros amd cons
I know leveled tires will be way more expensive, amd gas mileage will suffer. Isk why i had the urge to level it beaides mybe going off road which i really dont do.

My truck also has 3.31 gears which is a buzz kill for bigger tiresz

Aghhh decisioms

 

What are leveled tires? We level the suspension, never heard of leveling tires.

The bigger tires tht come with leveling lol sorry. I would run 275/65

 

Willing to bet you could find a nice set of 20" take off wheels from a Lariat or King Ranch around and just put those on.
I ran stock 20's with a Bilstein lift for about a year, never bothered me a bit. Rode nice.

 

With your truck being lowered, I don't see any advantage in going with bigger tires unless you're going for that against the lip look.

I added 6/10ths diameter over oem with 3.31, I couldn't butt dyno the difference, but you are looking at over 3x the increase that I did. You will be changing your effective diff ratio to about 3.10, lower than the lowest ratio Ford offers for the F150, available only in the 3.5 eco. As an owner of a 5.0, definitely not the direction you want to be going.

 

But wait! He's got the 10 speed, I went from 32's to 34.44, 315/70/17, on two trucks, one, a 3.5/3:55, and a 5.0/3:73, both with the 10 speed. The take off power with either was barely noticeable. Now I won't say with a 3:31 it won't be a bigger difference, but with my worldly experience I don't think it will be as bad as thought.

 

Left !
when in doubt always turn left.

 

Thats what im worried about. If i go to a 33x12.50 or a 275/60 my mileage insnt going to be as good. The 1001sp kit i have rides good for what it is, i just miss the level look and visability. Thay and i ran into a set of bilsteins front amd rear for a steal.

 

It will be like driving a 6sp 5.0. Can't count on either hand the number of owners that said they thought their 6sp 3.31 5.0 felt as sporty as it should. TITO, but OP says he wants to restrict mpg loss.
