PROPER AIRCRAFT TIRE SIZE SELECTION--OPTIMUM PERFORMANCE WITH MINIMUM MAINTENANCE

High speeds with heavy loads characterize the operating environment of tires used on business aircraft. In order to design tires which can withstand these operational dynamic forces, the engineer must select the proper tire size, incorporating the necessary design features into the tire construction, and thoroughly testing the tire to ensure compliance with performance requirements established by the airframe engineer. Tire construction considerations include tire carcass (beads, body plies, reinforcement plies, and liner), tread, and sidewalls. Tire size description/designation is explained, including ply rating and speed rating. Tire size selection criteria include tire/gear/airframe size relationship, wheel-well space, braking capacity, strut configuration, gear geometry and loading, flotation (contact area and inflation), speed requirement, water deflection, tire weight limitation, and replacement availability. Tire testing requirements are outlined. Proper selection of tire size results in optimum tire and aircraft performance with minimum cost for both airframe manufacturer and end user.
