The cost of changing a damaged tire is usually less than fixing the results of a catastrophic failure on landing. Annual and other inspections should always include a complete examination of your aircraft's wheels and brakes. Most general aviation wheels are comprised of two halves that are bolted together. Should any come loose or break, additional stress is placed on the other bolts, usually resulting in a failure. Keeping dirt, grease and brake dust off the wheels helps prevent wheel failure.
Pilots can use dry cleaning fluid and a soft brush to remove any buildup.
