Welcome to the forum, thevatch.
It is possible to use a mismatched tube/rim combo if you are using presta (need unscrewing the valve seal to inflate) in a rim drilled for a schrader (spring loaded valve like a car's valve). The hole in the rim is larger for the schrader valve leaving an area around the presta's valve stem unsupported under pressure.

BTW if your rims are drilled for schrader, and you are using presta tubes, there is a small adapter that can be used. They are available at almost any good bike shop.
