Depends on the weight of your boat and # of axles to determine class size. Take the weight of your boat, trailer and gear and divide by the number of tires on your trailer. Then look at tires that will support that much weight. You may want to go up a class if you are close to the max rate, but I would not spend the extra $ for a D rated tire if I were well under a C rating. The same would be true for a B rating vs a C rating. As for a ST vs LT, the ST is designed for trailers and the LT for trucks. Unless The LT's are "significantly" cheaper I would stick with the ST. If you are purchasing new tires I would get the ones recommended for the trailer. I would not worry about a $20.00- $30.00 difference in price, however, if the price difference is $100.00s then you may want to look at something that will suffice.
