Ron, the waterbed is waaay too much weight. Many homes and apartments will not stand a waterbed, at least on the second floor. Not only do you have almost a thousand pounds of water, you also have several hundred pounds of particle board, and steel framing. Even if (and it's a big if) the frame of the trailer will stand the weight, you will almost certainly have a negative tongue weight, which makes a very unstable, even dangerous, tow. You MAY be able to get away with a waterbed frame, and air tube mattress, if you can find one in the proper size.
Your second question is easier to answer, you need tire size ST225/75R15, load range D. ST is a trailer tire, you need to use it instead of, say, an LT (light truck) tire, as it is constructed differently, with different rubber compounds for the unique conditions encountered for a towed trailer.
If you want a numerical tire, a 7.00x15 D tire will work, they are only available in an LT tire, though.
