The performance characteristics of four 24-inch wheelchair tires are considered; one pneumatic and three airless. Specifically, two new airless polyurethane foam tires (circular and tapered cross-section) were compared to both a molded polyisoprene tire and a rubber pneumatic tire. Rolling resistance, coefficient of static friction, spring rate, tire roll-off, impact absorption, wear resistance, and resistance to compression set were the characteristics considered for the basis of comparison. Although the pneumatic tire is preferred by many wheelchair users, the two new polyurethane foam tires were found to offer a performance similar to the high-pressure pneumatic tire. In addition, the foam tires are less expensive and lighter in weight than the other tires tested.
研究了四种24英寸轮椅轮胎的性能特点；一种充气轮胎和三种免充气轮胎。具体而言，将两种新型免充气聚氨酯泡沫轮胎（圆形和锥形横截面）与模制聚异戊二烯轮胎和橡胶充气轮胎进行了比较。滚动阻力、静摩擦系数、弹簧刚度、轮胎滚落、冲击吸收、耐磨性和压缩永久变形阻力是作为比较基础所考虑的特性。尽管许多轮椅使用者更喜欢充气轮胎，但发现这两种新型聚氨酯泡沫轮胎的性能与高压充气轮胎相似。此外，泡沫轮胎比其他测试轮胎更便宜且重量更轻。
