Wheel Question

Hello!
I have a 1965 F100. My brother has a set of like new Ion 138 wheels from an AMC Javelin that he is offering to give me (AMC used Ford bolt patterns so they will bolt up). While I originally wanted to stay with the chrome smoothie look - these are FREE. I have 3 questions;
1) Will this 4.25" backspace work with my F100?
2) What is the largest tire I can put on this 15 x 8" rim on the back?
3) How do you think these will look on the Slick (opinion)?

Bigfoot - The backspace should be fine on your truck. You will probably learn that the bolt pattern is different with the wheels being 5 on 4.5 and the truck being 5 on 5.5. Still you can use adapters if you like the wheels. As for tire size, you have all the room in the world on the back. My truck is running 275/60/17's, on 9.5 rims. These tires are just under 30" tall and there is plenty of room for heigth. I did trim the ribs on the wheel houses this weekend to resolve a rub on the inside.

Hmmmmm did not know that about the bolt pattern - THANKS for the heads up. I guess it is still far cheaper to buy adapters then wheels. Are adapters safe to run? I have heard bad things about them in some circumstances?
Will this still fit with the adapters? They are 1.25" thick..

Bigfoot21075,
You know that running 1.25" spacers will require you to change your lug studs to longer (expensive) lug studs, correct?
By spacing out your wheel/tire that much, it will extend the tire out of the center of the wheel well and MAY cause tire sidwall interference with the outer fender lip.
Also by spacing the centerline of your tires out that far, it will put additional binding pressure on your wheel bearings.
Good Luck!

Hi Barnie!
No, I did not realize that. The spacers I was looking at bolt onto the existing lugs and have new bolts offset from the originals - either way I do not think this is the way to go. Back to my original thought for a nice set of red powder coated smoothies with chrome sides and moon caps....
It just adds up to more $$. I wish the last person had taken care of my existing (severely pitted) wheels...
