Airless Tires: A Leap Forward in Mobility

Safety accidents caused by pressure imbalance in traditional pneumatic tires are common, but airless tires offer "active protection" thanks to their unique structure. For example, the Michelin UPTIS airless tire utilizes an "elastic support matrix" composed of high-performance resin spokes.

Even after being punctured by a 10mm steel nail, it can maintain 95% of its load-bearing capacity, allowing it to continue safely driving for at least 80 kilometers, giving the driver time to respond to emergencies.

Zhengxing Wheel's honeycomb airless tires have been tested in extreme environments, ranging from -40°C to 85°C, and have shown no structural failure after 150,000 kilometers of driving. This completely eliminates the risks of traditional tires, such as low-temperature pressure drop and high-temperature blowouts.

This "blow-free" feature has led to widespread use in safety-critical applications, such as military vehicles and mining machinery. Jiangxin Technology's explosion-proof airless tires have become standard equipment on many military vehicles, ensuring trouble-free operation in complex terrain.

Pneumatic tires require regular pressure checks, patching, and replacement, which is both time-consuming and costly. Airless tires, on the other hand, are virtually maintenance-free. In terms of durability, Jiangxin's airless tires offer over three times the wear resistance of traditional tires, reducing the lifespan of a single tire by two replacement cycles. For shared e-bikes, for example, this could reduce the production and replacement of 20 million tires annually, lowering maintenance costs for operators.

The advantages are even more significant for commercial fleets: JD Logistics' AGVs equipped with airless tires have seen a 37% decrease in failure rates and a 22% reduction in operating and maintenance costs, effectively improving logistics efficiency.

For future passenger vehicles, the UPTIS tire, jointly developed by Michelin and General Motors, can completely eliminate the need for pressure checks and patching. It is particularly well-suited for autonomous vehicles, ensuring "zero-interruption" travel and reducing driver investment in both time and money.

The environmental breakthroughs of airless tires span the entire production, use, and recycling chain. On the production side, Jiang Xin utilizes 3D molding and nanotechnology to increase raw material utilization to 99.2%, reduce the defective rate to below 0.1%, and achieve unit energy consumption 10% lower than the industry average, minimizing resource waste.

Linglong Tire's lightweight airless tires weigh only 3.2 kg each, and their low rolling resistance design can increase electric vehicle range by approximately 8% and reduce energy consumption. In the recycling process, Jiang Xin's "waste rubber complete recovery technology" converts used tires into rubber composite microfibers that can be directly used in new tire production, creating a closed-loop industry chain.

This reduces raw material costs by 15% annually, alleviates the environmental pressures posed by the 1.5 billion discarded tires worldwide each year, and provides a new path for "urban mining" development.

Existing Shortcomings of Airless Tires: Restricting Widespread Adoption

1. Performance Balance Needs Optimization: Comfort and handling have room for improvement

Early airless tires were criticized for their high rolling resistance and bumpy ride. Despite continuous advancements in material technology, they still lag behind traditional pneumatic tires. Currently, Michelin's UPTIS tire, through the use of thermoplastic polyurethane (TPU) and nanocomposites, boasts a rebound rate approaching 90% of that of pneumatic tires.

The topologically optimized honeycomb structure of the Zhengxing wheel improves bump absorption by 40%. However, airless tires still exhibit poor noise control at high speeds. In some models, in-vehicle noise levels are 3-5 decibels higher than with traditional tires. Furthermore, airless tires offer slightly inferior grip during emergency braking and sharp cornering, especially on slippery roads. Braking distances are 5-8% longer than with traditional tires, impacting driving safety. Further optimization of structural design and material formulation is needed.

2. High Costs: Price Barriers Limit Market Penetration

Currently, the production cost of airless tires is significantly higher than that of traditional tires, primarily due to the reliance on imported core materials and complex production processes. Data shows that airless tires are approximately 2.8 times more expensive than traditional tires. An airless tire suitable for a family car can cost over 2,000 yuan, while traditional tires only cost 700-1,000 yuan. This exorbitant price tag makes it prohibitive for ordinary consumers.

Although domestic companies are accelerating cost reduction through the development of alternative materials, with unit costs projected to decrease by 8%-10% annually over the next three years and key raw material prices expected to return to a reasonable range by 2025, they will still struggle to compete on price with traditional tires in the short term, especially in the mid- and low-end passenger car market, hindering their rapid adoption.

3. Insufficient Adaptability: Difficulty Covering All Vehicle Types

Current airless tire designs are primarily targeted at small vehicles, such as shared electric scooters, family cars, and automated guided vehicles (AGVs). Adaptation for heavy-duty trucks and large buses, which require higher load capacity, presents a significant challenge. Heavy vehicles require higher load-bearing capacity and wear resistance from tires. 

Existing airless tires, with their spoke or honeycomb structures, are prone to structural fatigue when subjected to heavy loads for extended periods, significantly shortening their service life. In addition, some special models, such as sports cars, have strict requirements on tire grip and response speed. The current performance parameters of airless tires are difficult to meet their needs, and exclusive structures need to be developed for different models. This will increase R&D costs and cycles, and delay the process of full-scene coverage.
