Gas mileage with 285/70/17’s

Not sure how the op dropped that much... 3 front, 2 rear with 285/70/17 nitto RG's. Also have added armor and drive with a lead foot averaging 17-19

 

Heading West through your state many years ago I thought half way across the state, this is damn near as flat as Michigan. Then around 30 miles in the distance there was what looked like a storm front. It was the Rocky's. Western Montana sure is beautiful country. We don't have much in the way of rocks here in the lower peninsula of Michigan so I can get away with sl's.

 

I am getting right at 20mpg on the interstate and 18 mpg around town currently, the roads in Louisiana are pretty flat. What do you think I would be getting with a 3-inch ready lift and 285s? Losing 2mpg would not really bother me, but anything more than that it just would not be worth with how much I drive.

 

lol yea, as soon as you go east past glacier it flattens out. Cut Bank for example. Hell, even close is Browning where it starts to flatten out. Super windy though. A couple years ago there were doing the roads up there when I drove through. Man, that was a painful drive. Any time they do roads up here it is.

Sounds about right. I'd wager you'd lose a couple mpg's but nothing crazy. A tune would probably bring you right back up a little. Do it!

 

Can someone chime in with 5.29s? Otherwise I will update in a month!

 

Do you have a link to any of the tunes man, I would definitely put a tune in it. I was looking earlier for one mentioned a different thread but was not able to find it.

 

Have you been on the 5.29 thread? Tons of people running 33's there reporting decent mpg's. 5.29 Mega Thread and search within the thread for 285. I remember seeing someone post in there claiming almost 18 mpg.

KDMAX-PRO is the way to go!
