Hello 534ord,
You can get a replacement tire for your tractor at Tractor Supply Stores (TSC), or on the internet, ebay, Amazon, etc. Maybe even Walmart (although I've never tried them for a tractor tire).
Tell us what your problem is that causes you to need a new tire. You can't screw up with slime. It stays liquid inside the tire. The only problem that I can recall with slime is it plugged the valve stem of my hunting jeep once many years ago. I pulled the Schrader valve out of the valve stem, and replaced it. I run slime in many of my (low speed) tires.
