聚氨酯轮胎是将聚氨酯直接硫化在轮辋上的实心轮胎。聚氨酯是人造橡胶，但压缩系数高得多。与等直径的橡胶轮胎相比，聚氨酯轮胎的承载能力大约高两倍。聚氨酯轮胎是无痕轮胎。高压缩系数允许在某些窄通道车辆中使用较小直径的轮胎。
缺点：

• •由于车轮直径较小，减震效果较小。

• •驾驶舒适度较低。

优点：

• •更高的负载能力

• •更长的轮胎寿命

Polyurethane Tyres are solid tyres with the polyurethane vulcanised directly on to the wheel rim. Polyurethane is an artificial rubber but with a much higher compression factor. The carrying capacity of a polyurethane tyre compared with an equal diameter rubber tyre is about twice as high. Polyurethane Tyres are non-marking tyres. The high compression factor allows the use of smaller diameter tyres in certain narrow-aisle trucks.
Disadvantages:

• • less shock absorption because of smaller wheel diameters.

• • less driving comfort.

Advantages:

• • higher load capacity

• • longer tyre life
