Not with their tractor tires, but when I was really hard up for cash some years ago, I tried their motorcycle tires and was not happy with them. There's a reason they're cheaper than other brands, and why motorcyclists call them "Cheap S**t".
To be fair, maybe their quality has improved since then, maybe they are no longer manufactured in the Chinese Gulag, and maybe a tractor is a non-critical application where you could afford to skimp on tires - but I wouldn't ever buy them again for anything.
