I love the way either looks with the 4" lift and I probably looked at every damn picture on the internet when trying to figure out what to do. I went with 35's, but I have the bullnose so they probably fit a bit different. I think yours would look sharp with 33's if I have to pick!

 

I don't want to throw water on this but have you thought about what gear ratio you have. 35's and 3.55 is no fun unless you're crawling around a mall parking lot.

I'll be regearing over the summer.

 

go BIG

 

I vote 35's

 

4” with 33s. Less stress for the gears and still looks good.

37s. Install now trim later

 

Nah. I traded a set of 37s today. Too big.

 

35s, I run 33s on my stock bronco.

 

I vote 33s. Maybe 33 by 10.5 too. That's what I may go for when the Bronco is finished, well "finished". I don't plan on any lift for mine. Want to save the money and energy towards traction and road manners instead. This tire and wheel business is complicated.

 

35’s if your regearing

 

40’s

 

I second this comment. In all seriousness, go with 35s. I was running 33s on my stock bronco and when I went 6' lift, they looked tiny and weird.

 

You can get away with 33's without re-gearing, especially since you have a 351. If you are already planning to re-gear, just decide how big you want to be and plan from there. 35 and 6" lift is a commitment, 33 and 4" lift is more daily-doable, IMHO.

 

33s look too small to me on a 4" lift. Isnt your spare a 33?

I have a set of worn and crumbling 36" swampers on 5 lug wheels we can test fit.

Yeah the spare is 33" so that's kind of why I was leaning towards them.

33s with 4" BDS lift. glad I didn't go with 35s as I think there would be some rubbing when flexed or at full turn. these don't hit anywhere, look good and great for daily driving. I have Detroit tru tracs front and rear with 4.11 gears. very happy with my set up.

 

Huzzah! I'm looking at doing almost exactly that!. Already have a 2" lift, found a good used detroit truetrac for the rear and will be swapping in 4.11 gears. Then looking at doing 33s. How do you like driveability on the highway with that combo?

 

Here is another BDS 4" with 33x12.5R15 BFG A/Ts for comparison (and everyone loves pics).

 

That looks about perfect.

 

35's and 4.10's all the way!!!

 

OP go with 33s, I feel like that's what you really want. Although my truck isn't finished, I feel that my 37s are looking small already. Imho it's better to go a little bigger jic you get bored. The ttb will certainly handle the 35s so you're good with either 33 or 35. From experience, it is always easier to sell larger tires than smaller tires, unless it's a 44"+, lol

 

I'm putting 35s and 4.56 on mine with 4 inch lift. I like the fenders full though.

 

4" with 35s

Stock F350 with 33s. Same height as a bronco on 4" lift springs.

35's look way better

 

I have a 4" lift, 4.10 gears and 33x12.5x15.
Some 35's may not rub, but some will. I ran some 35" Boggers for a while. I did some trimming and they still rubbed.

33's

35" Boggers

 

The lift is now completed, and the 31s look a bit small! I prefer as big of tires as possible, but 33s will look good on it. And give plenty of flex without rubs

 

31s for reference. Going with 35s. Bringing it back from the dead as I'm finally pulling the trigger soon

 

One thing I didn't care for when I ran the 35" Boggers was the power loss. Even with my 4.10 gears it was sluggish. Then again I only have about 200 hp to work with here. My other truck came stock with 450 hp and 510 ft lbs. of torque. With my 33's and 4.10s the power level feels close to stock. If you go with 35's I'd go with 4.56 gears

 

Boggers are heavy, and much of the weight is the lugs, so the weight is far away from the central axis. They are power hogs for sure.

35s are great with 4.56 or even 4.88 if you have overdrive. All the f250/350 ive had have been 4.10 gears and 33s. It is a great combination.

 

Hell... I'm running a 6" lift on 33's and 4.56. I'm good with the setup. Looks a little odd but works for me. The only real loss is a little axle clearance but much easier for my 5'6" gimpy ass to get in and out of and wheel clearance galore.

Here's the back of my rig standing next to @RicoBronco w/a 4" lift on 35's...

 

Mine is an 89 with the 5.8 / C6 combo and a custom 4 inch lift (I pieced it together myself), C&T beams. 35 inch General Grabber A/T2 tires. 4.56 gears with detroit true trac diffs front and rear.

35s do look good. Most people's photos aren't a straight side photo so I appreciate

How do you like the soft top? I'm on the verge of ordering one. Taking the roof off is such a pain.

 

Guess who has to buy new wheels to fit 35x12.5 tires.

 

Again!? 35×12.50s will fit on 8" wide wheels

 

Whether you are getting 35x12.5x15" tires or 35x12.5x17" tires they both require/recommend a 8.5"-11" wide rim. Could you fit the 35x12.5x15 tire on an 8" wide stock rim? Yes absolutely but depending on the Pressure in the tire (to high) it could wear out the center faster. The lower the air pressure in the tire the more it flexes the harder you make a turn and is not responsive to steering input. That was one of the reasons (the Major reason) of the Firestone Debacle Ford had with Rollovers way back when. Ford only called for 26lbs of air in the tire to make it ride smooth but that wasn't enough to keep the tire from rolling under and catching an edge on an emergency maneuver/turn also the lower pressure caused a lot of tire/belt flexing which in turn caused tire temperatures to rise and cause belt separation. BFG All-Terrain T/A KO2 and General Grabber ATX 35x12.5x15 tires both call for 35psi Max. the same model tires above in a 17" tire both call for 65psi Max. Just giving some reference info to make a better decision and a Safer one also. Good luck.
