Simiar to jd5203 recommendation. Tire Shield from Midwest Equip is pumped into the tire via the valve stem. It uses kevlar fibers to seal and repair the puncture. I use it on all of my equipment as our place is covered with hedge and black locust trees. I have not had a flat on any piece of equipment that I have treated. It is more pricey but it sure works. They have some interesting videos about the product on their website.
That's what it is, the price for this stuff will save you thousands that you would spend replacing your tires.
