This paper analyses evolving end-user demand and willingness-to-pay (WTP) across China's passenger and commercial vehicle markets, delivering commercial-driven insights aligned with the conference theme of Making Innovation Pay. Against a fast-shifting industry landscape from policy incentives to pure market-driven consumption, vehicle electrification, digital transformation and sustainability are reshaping tire purchasing logic and premium acceptance. For passenger vehicles, fuel car consumers prioritise reliability, aftersales accessibility and total lifecycle cost, showing low tolerance for excessive brand premiums. In contrast, new energy vehicle (NEV) owners demonstrate significantly higher WTP for upgraded tyres featuring low rolling resistance, noise reduction, lightweight structure and enhanced load capacity, accepting 15-30% product premimus for measurable improvements in driving range and comfort. Market segmentation confirms a robust mid-end price band as the mainstream profit zone, while green and sustainable tyre attributes have gradually become valid premium drivers among urban and young customers. For commercial vehicles, purchase decisions are fully TCO (Total Cost of Ownership) oriented. Fleet buyers prioritise energy-saving performance, durability, retreadability and carbon reduction value rather than upfront procurement cost. Sustainable and low-carbon tyre solutions deliver clear economic returns through reduced fuel consumption and extended service life, converting ESG compliance into tangible commercial value. The study concludes that tyre innovation profitability no longer relies on theoretical technology iteration, but on scenario-based, customer-perceivable value. It provides actionable market-entry and product pricing strategies for global tyres players to monetise technological and sustainable innovation in China's rapidly evolving automotive aftermarket.
