Even though a passenger tire might fit a trailer, it is definitely not the correct equipment to use on your trailer.

Passenger tires have sidewalls that are a little more flexible than trailer tires because they have to account for the passengers in the vehicle. Since there should never be a passenger in a trailer, trailer tire manufacturers build there tires with stiffer sidewalls to better handle the heavy loads that are put into trailers. Because of this you will want to use trailer tires.

Since you will be putting them on a boat trailer I also recommend looking at a tire/wheel combination that utilizes a Galvanized wheel, like part # AM32397. The Galvanized finish on the wheel gives it a superior coating to fight rusting and corrosion over the average coats that your standard wheel has. Be sure to get a wheel with the proper bolt pattern. The part that I recommended comes with a wheel that has the common 5 on 4-1/2 inch bolt pattern.

I have attached a review video and a helpful article for you to check out for more information as well.
