Decided the rear tires on my Farmall M tractor have hit their due date, due to the cracks etc. New rear tires ordered. Only $740 each, 13.6 X 38, check it out. Having manually replaced tractor tires, and having gotten a few more birthdays, decided let the tire fella do it. First tire, no problem. Second tire, problem, tube rusted to the rim, big time. Pulling it free revealed multiple rust holes thru the rim. Spent a week running down another rim, used rim, as the price of a new one is 550 to 600 dollars plus shipping. Painted my new, used rim, now waiting for the tire guy to come out.
