What Tire Pressure for 4.80/4.00-12 4 ply CK2112? I have an old boat and trailer with these tires and I am relocating the boat from RI to VA. There isnt a pressure rating on the tire.

The Kenda 4.80-12 Bias Trailer Tire with 12" Galvanized Wheel - 5 on 4-1/2 - Load Range B # AM30590 is a similar tire and has a max rating of 60 psi. I can't confirm that your tires will be the same without the rating listed on the sidewall. You may want to consider changing the tires because they are old and do not have the max psi rating listed on the sidewall. If there is no speed rating listed, you also will need to consider 65 mph your max speed. I've attached an article to assist.

Since tires vary based on manufacturer, I can't give you a recommendation, but can tell you that all of our current tires the sizes you gave with the ply rating you gave have a 60 psi max.
