If you don't want to run tubeless tires, then I'd send it back. Not certain, but expect there might be some risk of a regular tire blowing off because of the different bead shape. I've run tubeless and it was okay. You can run a tube inside a tubeless tire is you like. Especially if you ever get a flat that won't seal.
Why are you even posting this drivel if you aren't sure?
Not certain, but I think posting on bikeforums increases your risk of heart disease and thickens the hair inside one's ears.
