I own a Roadmaster Tow Dolly and had regular tires on it when I bought it used. They gave me nothing but trouble. I then checked around and was told they have to be trailer tires as trailer tires have a different sidewall than regular tires. After all a tow dolly is like a trailer as it has to corner and hold weight.
Therefore I recommend trailer tires for your tow dolly. I also recommend you purchase a spare tire and wheel for it. If you have a flat tire then road service will have to bring a tire and charge you for mounting and the tire.
Hope this answers your question.
