My last truck was '13 a 5.0 S-cab with the 3.55 gears, I put 35x12.50 Hankook dynapro MT's on it and it really dogged the truck down, noticeably. Now I have a '15 S-crew 3.5 EB with the 3.55's and am tire shopping. I would like to run 35's but am considering something more like a 33 just because of how badly the 35's affected the 5.0. I would not run 35's on a 5.0 with the 3.55's again. Will the 3.5 EB suffer as much as the 5.0 with 35's or will it not be as noticeable with the extra torque it has?

The 3.5 will have alot more power and torque. It will just affect you gas mileage. If you don't care about that go for it.

I will be lifting mine and putting 275 65 20 34" but same width as stock. BoozeDaily put 34" on his 2.7 Eco and they are doing fine. 3.5 Eco even better.

I have 35s (315/60/20) and the 3.5 ecoboost and it has absolutely problem with the tires. I had a 5.4L V8 in my last ford and it had a little problem getting up and going.

Same mine screams with 35 toyo mts and the 3.5 with same gears as you. Just put the 5 star performance tune on and it's crazy how fast that truck is with 6 inches of lift. And I'm still getting 18-19 on the highway

Thanks for the responses, I feel much better and think I will go with the 35's again. I am waiting on my Tunes from 5 Star, my X4 came over the weekend.

They are great down there at 5 star. I called Mike at 9 am on Friday to see if I could get my tunes before I left for a weekend road trip and he assured me no problem. By 945 they were in my email. Really impressed overall with their product as well!

My tunes just showed up in my email a couple hours ago, can't wait to get out of work and load up the 93 performance tune!
