roll it down the hill... and have a few real live horses pull it up a hill... you'll be alright, lol. actually idk what you could do... 4.10s kill mileage.

 

i heard 4.10s would be good in city but bad in highway, i never go over 2500rpm maybe i need to set my foot for 2000rpm to see if anything happens.

 

You're getting 5mpg more than me! LOL

 

My silverado gets right at 20mpg on the highway, but thanks to the 4k stall I get less than 5 in town. On a full tank of 93 oct. I get almost 120 miles before its empty again.

 

I am getting around 16-17 on the highway cruising at 65, if I go above 70 it drops to like 14. In the city I get 12-13mpg. I also have 4.10s and the mods listed below.

 

I was getting right at 10mpg with 4.10's and stock wheels, now with the 33's its almost 12, Im pretty happy about that, dont really do much highway driving but Im sure that is going up too. I did notice that cruising at 45-50mph Im now below 2,000 rpm in the city, and Im sure that has everything to do with it.

 

man... we all get some horrible gas mileage, i guess thats the price we pay for having high performance pigs

 

What type of driving do you do? I recently got 18.5 mpg in my truck on the freeway = 2000 ECSB 4x4 5.3 3.73. My city mileage is terrible, which comes from the fact that I make many short trips and have a heavy foot.

 

Nothing but Highway.... Hell I live at least 35 miles to the nearest Wal-Mart... Yes, I live in BFE but I'm from H-Town.

 

Just a thought but did you have the speedometer recalibrated for the oversize tires? If you didn't then you're actually getting more mileage than what its reading because of the size difference. Larger tires do cost gas mileage as well; a little bit larger helps mpg but if they're too large they eat mileage.
