Flat tires can slow everything down, especially mowing the lawn. Even though the flat tire is annoying, it can be fixed very easily. When a lawn tractor tire goes flat the process for refilling it is similar to refilling a car tire. The major difference is to make sure the lawn tractor tire bead is still in place. Whether the bead remains in place or not, it should be easy to refill the tire and continue using the tractor.
Jack the mower up until the flat tire spins freely. Most mowers have to be jacked by the frame in the front or back.
Hit the tire of the tractor while turning it slowly to make sure the bead is in the proper place. The hits should be on the tread of the tire in the middle. This will make sure that both beads are in place.
Fill the tire with air from the compressor. Make sure to check the pressure every ten seconds to make sure it is not over-filled. Most lawn tractor tires require no more 20 pounds per square inch (psi).
Lower the tractor back to the ground.
