Best tire size for my 64 F-100

-4 Degrees, the motor was down 2.5...I havent driven it yet but we set my buddies dad's 55 up that was and he hasnt had any issues with vibe or bind

 

My '66 F100 had 15x6 fronts with 215/75/15s, rear was 15x8 with 255/70/15. I didn't do 7s in front mainly because '65-72 F100s always seem to have such a wide track front end compared to the rearend, so I wanted to make it up with wheel offset and width to even them out visually. Those offbrand fivespokes I found at a swap meet had minimal dish and kept the tires inboard. Front power drum brakes, power steering, and steering column were all robbed from a '69 F100. Daily driver for several years, until our second child was born

 

I need your advice for my backspacing on ford truck.Can I use stock ford rims with large tires and still clear my frame on rear?All these posts are gfeat but are they stock rims and what is the Ba ckspace?I have 48 f1 with 16x4.5 rims I want to change to 15" stock ford or early dodge,tire size 225/70/15 front and 255/70/15 rear.I have 3" backspace on stock original wheels,can I find the same backspace. and put larger tires on,without fitment issues?Thanks

 

Has anybody had any luck lowering the rear with out notching the frame, or cutting a hole in the bed?

 

Anybody?

 

Here's a couple.

My '57 has:
205/70R15 in front and 235/70R15 on the rear. Both on 15x7 wheels.IF I had it do do over, the rears would be 255/70R15 on 15x8 wheels.

My '61 has:
255/60R15 in front on 15x7 wheels. The rear has 275/60R15 on 15x9 wheels. The fronts are too wide but work for rolling it around for now.

LRS30- everthing that ive seen that goes spring under has about 1.5-2 inches of travel until you hit the frame. So Id say its a no go, when I flip mine I will c notch it with 5 inch pipe. With that the bed does not get touched at all.

 

I did a 5" pipe c notch and it bangs like nobodys business. lol, I really am considering a crown vic sub and cutting into the bed (bags) so it doesnt drive like a tractor

 

Bringing this one up
Looking at putting the new production American 5 Spokes on this 64.

I'm looking at 15" and considering 17".

But we don't need to talk about that if it's to far outside the accepted practice on here.


Plan on a dropped axle with lowered springs and flip move the rear on top of the springs along with a C notch.

I probably should lower it then buy wheels and tires.

 

How did you lower the truck?
