How much will 35s affect gas mileage

I plan on putting on some 35X12.5r18 soon and I was wondering how much my MPG will drop?

 

Will you be re gearing? @Acerwin can you help him out?

 

I have heard it can affect it pretty significantly, as well as loss of power if you don't regear. I'm thinking 35's as well for me when I redo my suspension but I'll only go that route if I regear

Depending on your driving habits and if you're currently stock, anywhere from a good bit to lots.

Expect 3-5 mpg to start.

 

alot

 

For starters if your worried about gas mileage you shouldn't be putting 35's on your truck...... Just saying......

 

I went from 265, to 285, and I felt loss of power and gas mileage. But I'm happy

 

yeah, i would bet you wont get 200 miles to the low gas light

 

It's not that I'm worried I'm just curious to how much I'll lose. I wouldn't re gear it right away but re gearing would for sure come shortly after.

 

I'd figure on 40% loss of whatever you get now.

 

I'll get just over 200 miles to a tank on 35s with no regear (yet).

 

Damn that's actually really good for being on 35s

 

With all my armor and stuff my last tank I got 215 miles out of it before the light came on.

 

With 285s I got 15-18mpg. with 35x12.5s I get 10-12mpg mixed driving with both.

re gearing did nothing for mileage for me. I get about 200 a tank with 4.88s

 

I've got a 16' 2.7L Manual 4x4 I went from 23.5 to 18.5. That is using GPS for calculation. I haven't regeared yet and that is with stock 3.92's.

Little 4-Banger pulls them pretty well, I assume the 4.0L will do much better.
