I’m going to be the first to say an open trailer is a completely different story because of weight. Heck on my first and maybe second open trailer I ran 20.00 mobile home tires
depends on the trailer and what you are carrying.
I have a 24 foot open trailer that is about 2800 pounds. A 900 pound 48 volt electric cart, and a 3000+ pound car sitting on it too.
cheap tires won’t work on it, right at 7000 pounds.
