Tire size

Hey all,

I am trying to find out if anyone knows what size tires would have come stock on a '78 F150 4*4 long bed. Thanks for any help.

Depends on what wheels it came with factory.

Wagon wheels? 5 slot alumium? What?

Unfortunately I do not know, it came to me with some partly rusted cheap chrome rims. Given the bare bones nature of the truck I would guess it was just the pressed steel wheels. It had 3.50 gears if that helps. Thanks.

I believe most 1/2tons run 235/75/15. But you can go as large as a 32x10.50 on a stock 4x4 1/2ton. A friend has a '78 F150 4x4 and runs 31x10.50 on 15x8 wheels and it looks great, more agressive looking than the stock size. But it's all up to you, it's your truck.

ahh thanks. That is the info that I was looking for. The reason I ask is that I am trying to figure out my speedometer. I have four inches of lift and 35" tires on my truck. Then I put in 4.56 gears. I have figured it out mathmatically but I was just curious what the original equipment was. Just for my information. Thanks.
