2017 3.5 ecoboost and 35" tires...
New truck: 2017 screw fx4 3.5 eco w/ ten speed tranny 145" wb, max trailer tow, 3.55 gears. I am getting new tires on tomorrow: 35"x12.50x20 with fat bobs garage 2.5" level and 3" rear block. My question is will the eb be able to pull the 35" tires without strain and still be able to utilize all 10 gears. I have read somewhere that a guy had 4" lift and 35.5 and couldn't get to shift past 8th gear. Just had me thinking. Wanting to make sure that it can still handle this tire load with stock set up. Thanks in advance

With as much torque as it has, yes you will cruise in 10th. Of course it will shift down more/sooner.
