What are you going to be hauling with it?
Figure out what the most weight you'll be putting on the trailer and go from there.
Lots of people don't get enough trailer. Or enough tire.
Recently upgraded to a 20' bumper pull with a dovetail and two 7k Dexter axles. Had them swap the 10 ply POS tires that were on it with Load Range G 14 ply tires.
