I have a 86 f350 and want to buy wheels, the old school bullit hole style. I don’t know weather to get 10 or 12” wide. I want them to be even or sticking a little bit maybe an inch from the wheel lip. With 33” tires, Anyone out there that has them can help me out?
2 things to think about here, well maybe 3.
The tires tell you how wide the wheel has to be to be safe. You are not going to put a 10 inch wide tire on a 4 inch wheel or a 15 inch wheel.
Tire Rack is pretty good on listing the tire sizes and what the wheel range the tire will work best in.
As a guess and this is ONLY A GUESS I would say 10 inch but check what the tire you are going to run need for a wheel.
A tire that sticks out side the body throws dirt and rocks all over the side of the truck, glass and mirrors. This can lead to rock chips in the paint that leads to rust and broken mirrors.
Also some states have a law how far the tires can stick out from the body.
Down here in NC if there is a law no one follows it as all the red necks have tires that stick out way to far for no reason that I can see as most are a street tread thin side wall not made for off roading. In CT the law was not more than 1 inch pass the body. That is why fender flares where made.
Also sticking out farther than factory puts more load on axle bearings to start and the steering parts.
So with that said do as you want with the information.

Oh also note bigger dia tire will change the final gear ratio.
Might be good if you do a lot of high way driving but stop & go is going to be a PITA
If you got a stick you will need to slip the clutch more from a stop to get going.
Auto the converter will slip more heating up the ATF and heat kills auto transmissions.
You can run a lower ratio gear in the axle(s) but that only helps on taking off from a stop and hurts high way driving.
This is where over drive helps. You can run a lower ratio gears in the axles for stop & go and over drive for high way.
Bigger tires weigh more too, so besides harder to get going it will be harder to stop.
so you see there is a lot to think about when you want to ru larger tires.

the wheel width will not hurt ball joints, it's the offset of wheel, or backspacing. if it's a wide wheel w a very low backspacing leverage will negatively effect your wheel bearings more so then ball joints but will wear them faster as well. how fast? i'm not saying every week your replacing ball joins and bearings, but it will cut the life, by how much is determined by how you drive and where. you can run a 12" wide wheel no problem if the backspacing is somewhat centered.
larger tires will effedt seat of the pants feel and some mileage. for sure, but these are old *** trucks and not the most fuel efficient to start w. if it's worth it to you go for it.
12.50" wide tires are safe safe mounted in a wheel at a minimum of 8-8.5" wide. a 12" wide wheel with 10.5-12.5" wide tire is doable, but not suggested. people do it often, doesn't mean it's the best or even good. but it is doable. don't try to air down though.
get your truck so you like it, understand the pros and cons and roll w it
Thanks for the reply, I’m restoring 86 f350 it’s going to be in the garage most of the time I was reaching out for wheels size just for the look of it. I like deep dish wheels but I don’t like the look of them sticking 2 inches or more
i like it too. you won't get the deep dish look without having a good w mount of wheel out past the outside of the wheel mounting surface. a 12" wide wheel with 2" back spacing willl have the same lip on the outside as a 10" wheel w 0 backspacing but the 10" wide wheel will be worse for the ball joint. i am running 20x12" on my super duty with maybe 4" back spacing and i love it. just enough to look tough and proportional but not roller skate-ish.
i would say for a stock or close to stock application a 10" wide wheel with 4" backspacing plus or minus would be fine.
Dont forget the larger wheels put more wear & tear on the steering too.
Tie rods, box and dont forget where the steering box bolts to can crack.
Seams to be frame cracking is more on 4x4's but can happen with ant truck with large tires.

I'd go with a 16x8 & 285/75-16. If it's 2wd, maybe even consider a 265/75. Personally, if i was going to tun any wider, I'd step up to a 20; lots more backspacing options to make it fit correctly.
