I'm curious what kind of mileage you guys are getting running 35s, deleted, and tuned. Mixed driving mostly. Also how much did it drop? Will it drop more with a small lift (3-4")
I was getting 18 after deletes and tunes in mixed driving with factory tires. Getting over 20 on road trips. Last month I installed a set of 35" toyos and now the best I can get is 15.5-16 in mixed driving. I know they are heavier tires but not much taller. I never thought they'd knock it down that much.
WOW! I sure hope I can get better than that towing. The main reason I decided to upgrade back to a diesel is because my f150 was getting 9.5-10 towing my camper.
It depends what you are towing. Our 40' toy hauler loaded is over 17k lbs and my 13 F350 is getting 9 mpg with that. 7 mpg with headwind or if I'm pushing it.
I had a tuned and deleted '12 6.7 with 2" level and 35 toyo MT. I would get 15-16 mixed driving and could get 18-19 doing 60-65 on the highway. My '16 stock mixed am only seeing 14.5-15.5 doing 65-70. Im trying to really leave it alone but its really tempting...
I guess I might as well forget ever getting 18-19 again then. I can't run 60-65 down the highway. Plus, even if I could ID get my *** run over here in Houston traffic.
One reason I'm happy with my 33.2inch tires If a 33 inch can't get you out or over neither will a 35 IMO and honestly on an 18in rim they look almost the same.
Buddy of mine has same truck/year/ratio except I have a 300 pound brush guard. we have the same tires and 5 star tuning now. I have 33s he has 35s I get on average 16 to 18 mixed. he gets 14 to 16 mixed. I get 20-22 hwy not trying to hyper mile he gets 17-19 hwy. If I hyper mile at 65 behind an 18 wheel I can get 30 all day
I didn't buy for mileage but I wont throw it away either.
I have 2.5" level kit and 325/60/20 tires (35.5x12.8 ) with a brush guard. Mixed I can't hardly get over 14. If I keep my foot out of it then I can get about 15 highway. That's tuned and deleted.
I have the 2.5" leveling kit on basically 35" tires and I'm only averaging 10 MPG accordingly to the lie a meter on the truck. Granite, I have less than 300 miles on the truck and that is all city driving no highway so my MPG probably don't count..lol
At least for me, the hit in fuel mileage upgrading from the stock Michelins on 18s to 35s isn't as bad as it seems since now my odometer is registering 1/10th per mile less than it should based on one of those "Speedometer Check Sections" on the freeway. The now inaccurate odometer will even throw off hand-calculated mileage, so if I'm now calculating a 12 MPG average, I'm really getting 13.33. Before the tire upgrade I was hand calculating around 14.5 MPG, so I basically lost a little over 1 MPG due to the bigger tires and my 2WD airdam, which seems reasonable.
295/65/20 Nitto trail grapplers stock height, getting 15 running 75 mph on street and hot street tunes. About 14 in the city. Pulling a trailer throw all of that out of the window, get about 9-10 mpg running 70-75.
2011 F-350 CCLB Deleted H&S mini max set on performance with 325/60/20 Toyo ATII and 3.55 gears..I just went from E central Ohio to Moline Ill and back..Cruise set at 76 on interstates plus 3 days of local driving while there my hand calulated average for the whole trip was 17.2 mpg..had 30+mph headwinds going out it averaged 16.1..coming home with tailwinds it was showing over 20 mpg
