Big tall 11 R 24.5 is my guess. They are not as common as the 22.5 used on today's semi trucks We have used Goodyear Marathon the last two sets. They age out long before cupping or wearing out. We only drive 5 to 7 thousand miles per year. We uae steer tires all the way around. With a basic tow a thousand dollars, I am not interested in seeing how much traction I can get . The tires cost us  360.00 each with tax and install, ballanclng beads ,old tire disposal etc in 2022. Many others in this forum have had good luck with Toyo
Enjoy your Newell
