Your tire should mount via 1/2"-20 lugs like what we see with the Kenda 4.80-12 Bias Trailer Tire with 12" White Wheel - 5 on 4-1/2 - Load Range C # AM30660. For this size and style (steel) of wheel you need to torque the lug nuts to be inside the 75-85 ft-lbs range.

I'm attaching a chart we have which shows the various torque ratings for different wheel styles and sizes.

Overpacking the trailer hub with grease is the number one reason for grease seal failure. For a boat trailer I would recommend re-packing the hubs by hand with grease once per season and you'd be fine. I don't like recommending people use…
