With more than 10 years of field testing and continuous improvements of the tyre structure, McLaren’s Nu-Air semi-pneumatic tyre series integrates the strength and stability of a solid tyre with the smooth, cushioned ride of a pneumatic tyre. With its lower cost/hour the Nu-Air tyre has become widely known as the smart alternative to foam filled tyres and regular pneumatic tyres, according to the manuafacturer.
Originally skid steer loaders and some backhoes were eligible for solid cushion tyres. For years OEMs and equipment users have been reporting higher equipment productivity and reduced maintenance costs derived from the usage of such tyres. The continuous positive results and the numerous inquiries about more other tyre sizes motivated McLaren’s R&D department to invest in new tyre sizes, and apply the semi-pneumatic tyre technology for heavy construction equipment as well.
Up to now only OEMs had access to a limited OTR range of tyre sizes. The company now introduces the full range both to the OEM and to the retail market. Thus, industry manufacturers and users of backhoes, telehandlers, front end loaders, wheel loaders, and wheeled excavators finally have access to the technology that was once available to compact equipment only.
The OTR solid cushion tyres are not only an alternative to foam filled or solid tyres, but to the heavy and expensive tyre chains preferred by many mining companies. The flat proof technology eliminates the need for tyre prevention, while the extra weight of the tyres provides the stability that is crucial on any harsh terrain.
There is a variety of patterns available, allowing customers to select the right tyre for their type of terrain. The RT pattern for size 20.5×25 has been developed precisely for problematic surfaces, where rocks, scrap and debris give a hard time even to the most experience operators.
The new sizes cover almost the entire OTR range.
