Question on possible wheel fitment

[TypeSL2]

I believe I have found a set of wheels the wife and I would like to use on our C10. I don't know if these wheels will work with the disc brakes though. What spec am I looking for to help me decide on what wheels to get? I know my factory wheels will not fit, but I am not sure why they won't. It was my thinking that the wheels would not fit due to diameter, but don't know for sure. If anybody has anymore info on this subject, it will be greatly appreciated.

Here is a link to the wheels in question.
