3.7 with 35s
 

I'm debating between leaving my 2012 ford f-150 3.7l xlt as is and throwing 33s, or jacking it up 6 inchs and tossing 35s on there. Only thing that worries me is if this mighty v6 is powerful enough to push these 4 35s effectively. Anybody have any input? opinions? Any advice is much appreciated.
Thanks!

I have the same truck ecoboost and I don't feel any major power loss.. Only thing that took a huge hit was my mpg!!! I average 9.9mpg to 11.1 mpg.. I have a 6" lift with 35s.. But I LOVE this thing!

I have 33's and didn't feel any loss of power. Next set will be 35's.

You have the 3.7?

You have way way more Toque than a 3.7 no comparison.


I noticed some difference on my 3.7 going from 235 to 265 17,s but I am pretty picky. Not enough to want to go back but I would never consider more. that said I am happy with the stock height. For you that lift and go big it looks cool and I see why you do it but just not for me.

Yes and I did not notice any loss of power.
My previous truck was a B4000 and I was running 33's. This 305hp 3.7 should be good to push 35's with the same gearing.

I have 305 70r 17 which is basically a 34" on my truck with the 3.7L it can handle it very well and it is worth being a little harder on gas. All i have is a leveling kit to make them fit , but i always ran bigger tires so i could not tell you if it is less powerful, i assume it is but I am not building a rocket:thumbsup:

I'm running Goodyear Duratrac 33s right now. I need to give it more throttle of course, and mpg went from 16 to 15.7. So no big deal really.
