Frequently drive your tractor across rough terrain? Tired of coping with flat tires after hitting a hard bump or going over some metal debris? Consider applying a tire sealant, a viscous, sometimes fibrous liquid that coats the interior of the tire. 

Tire sealant is often sold as a sticky, fiber-filled liquid that coats the interior of the tire with the excess puddling inside as well. If the tire is punctured, the escaping air carries the viscous sealant out through the hole and the sealant fibers create a plug. Driving with the punctured tire allows the puddled sealant to flow into and plug the hole.

Pump the sealant into the tire through the valve stem opening while a jack supports the weight of the vehicle or implement. Following your owners manual and the instructions on the tire sealant packaging, determine how many ounces of sealant are needed per tire. Note, however, that putting in less material than recommended will limit efficacy as the tire doesn’t contain enough sealant to stop a puncture.

Be sure to check the pressure of and balance the tires after applying tire sealant. If the sealant puddles in the bottom of the tire, it may cause imbalances when moving at higher speed or over uneven terrain.

Remember—some sealants work only with tubeless tires and cannot be used with tube-type tires.
