New Craftsman lawn tractors typically come with a two-year warranty. However, they do require that customers maintain their lawn tractors on a regular basis as part of their compliance and coverage requirements. This includes maintenance of tires. Check the air pressure regularly and check for wear and damage. There are a variety of methods for repairing punctured tires up to and including replacing them. In order to purchase the correct replacement tire remove the original and take it to an authorized Craftsman dealer.
Park the lawn tractor on a level surface, turn the engine off and remove the key. Place the tractor in park, disengage the blades and raise the mower deck to its highest level.
Place cinder blocks under the axles of the tractor. The blocks should be on their sides so that the solid side of the block is under the axle. This will lift the tractor up off the ground making it easier to remove the tires and preventing damage to the axles.
Remove the axle cover by sliding the end of a flat head screwdriver under the rim and carefully pushing down on the handle of the screwdriver.
Remove the retaining ring and washers. Remove the square key (found only in rear tires). Place the retaining ring and washers into a plastic cup to avoid misplacing them. Remove the tire.
Slide the replacement tire on to the axle. For rear wheels align the rear wheel hub and the axle. Insert the square key.
Replace the washers and then the retaining ring on the axle. Place the axle cover over the end of the axle and gently hit it with a hammer to secure.
