what is the bolt circle on my 64 f 100?

i have a set of chromies with 4-1/2 and 4-3/4 bolt holes, but they don't fit

 

That would be 5 on 5 1/2. Welcome to the site

 

I believe they are 5 1/2 X 5 on most.

 

It is a 5 on 5 1/2 bolt pattern. Wheels for that patter especially in 15 inch are becoming harder to find as everyone is going to larger diameter wheels with lower profile tires. Which I personally think looks like crap. American racing still makes a few different models of wheels with that pattern in15 inch. I wanted the Torque thrust wheel for mine and they have stopped making them. Fotunately for me Summit motorsports still had some in stock that they were sell pretty cheap and they paid shipping.
