I am looking at 2 34.5 inch tires they are 315/75 r16 All terains I'm looking at them because he doesn't want much for them and the price of 2 new ones isn't to bad I have as my user name says a 1986 f250 xlt 4x4 but what it doesn't state is that it is a 6.9 diesel which I know makes the front end sit just a little lower I'm wondering if they will fit at all without lift I know they will rub the leaf springs in the front during turning but other than that will I have clearance issues until it's lifted?

 

Stock I am almost 100% sure that you would have rubbing. You can clear 33's stock I'm certain about.

 

Thank you for the info

 

i have 315 75 16 mts on my 86 f-250 and the only rubbing it ever did was on the crappy old mudflaps which i have sense parted with, mind you with the diesal up front might be the difference between clearing and rubbing,

 

Thanks for letting me know I might see if he will let me just check them to see

 

Here is my 86(diesel) a 315s and 6" of lift. You do the math

 

I eventually want 3 inches of lift but I have to say that is one beautiful truck (I hope I can get my old girl looking that good again) I also have to ask do you know what Is used to seal your moon visor? I Picked one up at my local jy and the person didn't have anything sealing it and you can tell it was leaking

 

Silicone or rtv

 

There are a couple of guys on here that swear they can fit the military 36/12.5 R16.5 tires on F350s with stock suspension so it might be possible. I wouldnt think the F350 would sit any higher than the F250 although it kinda depends on how weak your suspension is if its hanging lower in the front or not.

 

Well after taking the engine out it only raised up about 2-3 inches

 

A solid axle f350 sits about 2" higher than a TTB F250

 

Yup, F350s sit taller thanks to the straight axle and flat springs (not neg-arch like the TTB springs) I have a set of military 37s on my stock 86 F350 6.9idi. Only trimmed a small piece off of the fronts of the fenders. Clears fine for driving, hauling and beating it around, at least until I can lift a bit for more clearance.

To squeeze 35s on a 250, you'd at least need to cut the front fender pieces like I did to not rub and smash them up, and even then you'll probably have issues. I'd say stick with 33s if you need new rubber, or buy these and put them in the garage until you can get money for the lift together.

 

Just for curiosity and I don't mean to steal your thread but will a shackle flip work on a TTB to stand the truck up high enough?

 

That's my 385 block powered F-250 with 245/75/16's an the front and 265/75/16's on the back.

 

I don't know the theory why they cannot be used, but people in the know say the shackle REVERSAL kit can only be used on a straight axle truck.


Also to the original poster that started this thread, I caught something in your first post. A lift will not keep the tires from rubbing the leaf springs. New wider wheels will though, and of course you need a lift to clear the tires if you are sticking them out beyond the truck farther with wider rims.
