This SAE Aerospace Information Report (AIR) applies to landing gear tires and airframe structure for all types and models of civil and military aircraft having tires as part of the landing gear.
This report describes the advantages and disadvantages of prerotating tires prior to landing, and explains why this practice is not generally adopted. Two potential benefits of this practice are considered: 1) Tire wear and 2) Spin-up loads on the landing gear and aircraft structure.
Rationale: The idea of tire prerotation at landing to reduce tire wear and spin-up loads has been proposed many times in the past, and continues to be proposed for new airplane projects. Yet, this practice has not been adopted in the aircraft industry. This report explains why this is generally not a feasible idea, and also discusses situations where it may be beneficial. This report is a compilation of all of the information available to SAE A-5, and comprises the general consensus from the aircraft and landing gear industry on this subject.
