I currently have a 3.5 in suspension lift and no body lift, running 33x12.5x15 right now. Rear end has 4.30 gears and tranny is a NP435. I am debating moving to a more modern 17in wheel and thought about 35s, 305s or 315s. My EB will see 95% street and hopefully someday I will take it on a trail run. I’ve read the 15s are better for off road and the bigger sidewall acts as suspension. Looking for anyone’s experiences and input. Will I need to add a 1in body lift for the street driving? I can see the obvious advantage of adding a 1in body lift for off road.

Re: Tire size debate
17s are the new 15.

Re: Tire size debate
15" wheels are sort of going the way of the dinosaur. My next set of wheels will be 17". For your purposes I think that decreasing sidewall is a good thing, a little less sidewall flex for on road handling is not a bad thing. And for off road you're not really losing anything like you might if you stepped up to 20" wheels. I have 20" wheels on my daily driver, with 33" tires and while I like the look on the pickup, it would be goofy and impractical on the bronco.
Just get ready to spend. Tire prices get higher on bigger wheels!1970 Bronco
