What kinda gas milage are you getting with 33/1250/20s or 305/55/20s?

[GM MAN VINCE]

I average 21-22 mpg on the highway right now and I'm wanting to do a 2.5" level with either of those size tires I will also be doing new wheels at this time also. I'm only interested in a all terrain as I drive my truck way to much on the highway for a mud tire. My daily round trip is 80miles.

 

Just wondering what everyone else is getting. I've driven my truck for 60k miles stock and it's time for a change.

Vince have a 2015 AT 6.2 with 33x12.5 Toyo RT's and get 19-19.5 mpg on highway doing between 63-67 mph. Average dropped 1.5-2.5 mpg with tires.

I lost 1 doing the level.

AT tires = more tread, noise, friction and greater rolling resistance.

Your ride will burn more fuel that's guaranteed but no one buys a pickup truck for fuel economy anyways.

Results will vary, expect anywhere from 1-3 as any of the other hundreds of threads have stated. Do you have a 4x4? That will matter as well, not sure being down in MS as most are 2wd.

Just got home from a 1,200 mile round trip, 99% was all interstates running 12-14mph over the speed limit and averaged 17.7mpg. Not too shabby for 420hp running 82-84 mph

I'm on a 2.5 level with 305-55 and I'm get 22mph mixed highway and city. Forgot to mention it's diablo tuned too. Without it I was getting 13mph

realistically 19-21 with a controlled right foot. u start taking the air dam off and take away v4 ur gonna be struggling to get 19.

I have the LT (heavy) Nitto G2 in 305 and a very heavy right foot. I get around 13-14mpg with a 2" front level. I probably average 14mpg tops on the highway (usually 80-85mph and hilly)

You gained 9mpg from the Diablo tune??? This makes me want to get it even though it would probably void my warranty...

[Hookedonhunting]

Would the tune void an extended warranty? I'm out of my bumper to bumper.....That's an amazing increase in mileage. I'm headed to Meeker Colorado from Atlanta GA this September and could use the extra mileage. I'm stock otherwise in my 15' 6.2 Denali on stock tires and 3:23 gearing.

This was like 3 days after tuning it. I'll try get another shot for ya. I am currently at 19k miles and said f the warranty. I'll just return it back to stock and take a 50/50 chance with the dealership

28.1 has to be the highest number I have seen on one of those! Downhill with a tail wind I recon.

[jimmyboy8301]

My friend with a level averages 17.3-19 depending...

 

Me with a 7" lift 35s I'm lucky to pull 15.5 usually aver 12.8 normally without watching the mileage.
