So I recently bought the hell bent steel 2.5 leveling kit&next week Ill be ordering some 315/75/16 tires now I know it will through the spedo off how much mpg will I lose?Will it be a rough ride?Im getting some all terrains not sure which ones yet.Thanks in advance!

 

on my 2500 my tires stock are 265/75/16 and when i have on 315/75/16 when my speedo said 70 i was doing about 78-80 i got 4 tickets over that ****

but thats my truck my buddy who owns a 2007 ford powerstoke(shame on him for buyin ford) he has a 6in lift and 37x1350x22 and his odo is like about the same off as mine...

so idk thats my 2 cents

 

For your year truck you can correct the speedo by changing the speedo gear in the trany/t case.

Expect to lose mpg and can't comment on how it will ride without knowing what tires you are going with.

 

my mpg was about 13 on the hwy but i got a aod and 4.10s and a 6500pound 3/4 truck.

i get much less can my plenum leaks.

 

Mine don't ride that rough and they're m/t's. You'll definitely lose some mpg and gain some noise.

 

i want your sport bumper

 

Basically a 35 inch tire..... what gears do you have? 3.55's? You aren't going to like that much around town......

 

I have 315/75/16s bfg mt's and my speedo is off by about 7-8 mph. And im pretty sure I have 3.55 gears and get 11 mpg and thats a mix of mostly highway and a little bit of in town driving. I wish I had $$$$ for 4.56's

 

Yeah, I hear ya on that. I am considering upping my tire size to 285's, but, I have 3.55 gears, and I WORK my truck on a fairly regular basis. (comes from being the only member of my group of friends with a pickup...... ooops.) I want to do gears, as it is one of THE BEST mods for these trucks, unfortunately, it is also one of THE most expensive...... and I live on a shoestring budget. (and a broken shoestring at that. )

 

My 315's definitely made me lose some power... I plan on getting 4.56's sometime in the spring, but the weight and size will throw you off
