help me if you know about cars - a tyre/wheel question

[spamuell]

I looked on google and I'm sure this is out there but I'm really astonishingly bad at finding it.

Here's the question: I have a tyre with no wheel inside. I have a wheel that is designed to fit inside the tyre. Is it possible for me to put the wheel in by hand? If so, is it safe to use?

Thanks for the help of anyone who knows this.
