Static Mechanical Properties of 30 × 11.5-14.5, Type VII, Aircraft Tires of Bias-Ply and Radial-Belted Design

An investigation was conducted to determine the static mechanical characteristics of 30 × 11.5 - 14.5 bias-ply and radial aircraft tires. The tires were subjected to vertical and lateral loads and mass moment of inertia tests were conducted. Static load deflection curves, spring rates, hysteresis losses, and inertia data are presented along with a discussion of the advantages and disadvantages of one tire over the other.
