OTR® NDX™ 350 MAG Air-Less UTV / Utility Tire

The OTR® NDX 350 Mag Air-Less Tire is a high traction all-purpose UTV and utility tire and a great OEM replacement!

Keep your utility equipment up and running — even under the worst conditions — with the OTR NDX 350 Mag tire and wheel integrated assembly. This isn’t your typical “no-flat” tire. The NDX RTV airless tire system is a patent-pending breakthrough in airless tire design and value. These assemblies feature an innovative run-flat design and construction that eliminates costly downtime from flat tires. Because the NDX is sold as a system – tire and wheel included – installation is simple. Integrated steel wheels are included with the NDX airless tire design, meaning you can bolt it right on just like a standard factory rim. It is highly important to please check bolt pattern and fitment details before ordering, see fitment chart below ↓.

Designed with heavy use in mind, the NDX lasts up to 2x longer than competitive airless tire options, even when carrying heavy loads and after sustaining damage. Thanks to its heavy-duty construction and 14-ply effective rating, this airless tire is ultra-durable and long-lasting for heavy-duty use. The NDX system ensures more value and a better ROI for operators. What’s more: because it is the tire that never goes flat, you won’t have to worry about flats slowing you down.
