PIONEERING FACTORS DRIVING DIVERGING TYRE TECHNOLOGY FROM CONVENTIONAL TYRES TO NON-PNEUMATIC TYRES

Non-Pneumatic Tires (NPT) are tyres that are not pneumatically inflated and are supported by flexible spokes and a closed construction. Several important reasons to upgrade from traditional tyres include maintaining the correct composition of internal air, avoiding excessive wear and tear, and avoiding unexpected damage. Several significant considerations to consider when selecting non-pneumatic tyres are their high rolling resistance, inability to flatten, and minimal maintenance. The combination of elastic polymer and composite materials results in excellent performance, and the asymmetric design enables non-pneumatic tyres to fulfil a variety of jobs, providing them an advantage over traditional tyres. The strength of the NPT is determined by its form and structure, and there are many sha pes and structures available for different purposes. Cost savings are achieved via the design of spoke structures and the efficient manufacturing of components. Airless tyres should improve by designing spokes in such a manner that the weight distribution is uniform, the cushioning effect is enough for appropriate vibration damping and vehicle dynamics stability, and there is no debris trapped between the spokes. The drawbacks of non-pneumatic tyres include heat build-up in the tyres and reduced suspension, which results in decreased driver and passenger comfort. This article will mainly discuss the many reasons that have contributed to the shift away from traditional tyres toward airless tyres. The issues discussed include the advantages of the NPT over traditional tyres and the disadvantages that must be addressed in the future via the adaptation of different architectures, forms, and manufacturing methods.
