I have a little Massey that needed tires when I bought it, in high school, 30 some years ago. It still needs tires. Major cracks and you can see the cords easily in many places. I even had it set up as a lawnmower for about 10 of those years. I wouldn't do that if a blowout would cause a problem, but for that tractor it would just be an inconvenience.
That said, I have had good service from BKT as a lesser expensive tire brand. When you are shopping, expect the import tires to be a little narrower and smaller diameter than their classic American counter parts.
