I'm 2wd screw, I've decided against going with the 6" and 35s because it's just not really worth it. I really want to run 33x12.5R20. What would it take to level it out and help them fit with a little room for flex. I was thinking 3" Readylift up front and a 1.5" Block in the rear. Thanks guys.

EDIT: Also, I assume from 255/65/17 to 33x12.5R20 My gas mileage would go from about 12 to 10mpg. Then I assume if tuned, It'd go up to around 12 with 33s and then if I regeared to 3.73(?) I'd go up another 1-2mpg?

 

I have a 2WD with the AS 2" Leveling Kit and running 285/65R18's on stocker wheels and love the look.
I have not noticed much, if any, gas mileage difference. I know my speedometer is off 3 MPH so I try to
only drive 70 down the hiway to keep from burning to much gas.

I am getting roughly 14-15 MPG all around with my current setup!

 

What does a 285/65 equal out to. I think it's about a 32.8x11? or something around their?

That's cool, what gears are you running?

 

keep savin , and lift it

it wont be worth it to go from 3.55 to 3.73 , id go with 4.10 atleast imho

 

Wouldn't 4.10s be worthless on 33s?

 

3.73 would make that much of a difference, you also said you do alot of stop and go / city driving . 4.10 would be better

The chart is divided into three categories. The rpm highlighted in black are optimum for the tire size and ratio combination. These will most closely give you the best overall drivability. If you're looking for a ratio that will give better fuel economy for highway driving at the expense of some acceleration and overall performance, choose a ratio in the yellow shaded area. If you're looking for a ratio that will improve acceleration and towing power at the expense of some fuel economy, choose a ratio in the blue shaded area.

 

Ah so which of those colors would do me best in city?

 

either 4.10 or 4.56

 

I want better gas mileage, not worse

 

I think they are roughly 32.6 by 11-11.5 something like that. I just have 3.55's!

 

Yeah, basically what I'll run. Yeah, I wish I had 3.73s but ya know.

 

I do too but not worth the money, time and effort IMO!

 

Ah 2wd, take it to shop, drop off, leave it for a day, 700 bucks. Boom haha

 

id drop it personally


also, do they make 4.30's for these trucks, that might just be the best gear for me

 

Drop my truck? No way, if I did that. I'd want bags, and 24s. Then my parents would call me a thug and stab me

Hmm, I think 3.73 or 4.10 would be good.
