Will Goodyear Trailer Tire 225/75-15 Inflated to 65 PSI Have Excess Heat Build Up

Question:

ilooking to upgrade to a E rated 225/75R15 trailer tire with max air pressure 80 psi. The load/inflation table says the E rated tire at 65 psi will carry my trailer weight. Will the E rated tires run hotter at 65 psi than the D rated tire65 max psi? Any blowout or separation risk with the E rated at 65psi? Can you rely on load inflation table of Goodyear?

Expert Reply:

I attached the inflation chart for the Goodyear 225/75R15 trailer tire part # 724857519 you referenced which I believe is your best choice. As long as you are under this tire's capacity when at 65 psi which is 2,540 lbs you'll not have to worry about excess heat build up or failure. You also will have a speed rating of 87 mph which is higher than most too. These tires are made in the USA, have an excellent tread design for wet and dry conditions, and have a great warranty as well.
