ZC Rubber has announced an original equipment (OE) collaboration with Xiaomi Auto, with its Arisun 1 Star tire selected for the latest Xiaomi SkyNomad N70 five-seat range-extender SUV.
The Arisun 1 Star in size 245/55R19 will be fitted as OE on all 19in versions of the Xiaomi SkyNomad N70 Pro and N70 Max.
As a five-seat range-extended SUV, the Xiaomi N70 places particular demands on its tires due to vehicle weight, range targets and the need for a quiet cabin. Based on ZC Rubber’s Phecda Tech System, the Arisun 1 Star was optimized across its compound, structure, tread pattern and manufacturing process. The development focused on reducing rolling resistance to support range, lowering tire noise for a quieter cabin and maintaining ride comfort and grip for both urban commuting and long-distance highway use.
Noise reduction was a key development target. The Arisun 1 Star uses 24 internal noise-reduction plugs and a dedicated acoustic chamber to reduce and disperse tread noise. A high-elasticity sidewall and optimized carcass structure are also intended to absorb road impacts and improve overall NVH performance.
To improve efficiency and range, the tire uses a newly developed low-rolling-resistance rubber compound to reduce energy loss while driving. It is combined with ZC Rubber’s BPOT Technology, which optimizes contact pressure distribution and increases the contact area by 5%. This helps promote more even wear and longer tire life while supporting the N70’s range performance.
The tire incorporates ZC Rubber’s Hybrid Formula 3.0 to enhance grip on dry and wet surfaces. Its optimized drainage grooves help channel water away from the contact patch more efficiently, supporting braking and cornering stability in wet conditions.
“Developing tires for electrified vehicles requires a careful balance of efficiency, NVH, grip, handling and durability,” ZC Rubber said. “The Arisun 1 Star for the Xiaomi SkyNomad N70 reflects our vehicle-specific approach to OE tire development.”
