Sumitomo Rubber Industries closed the third quarter of 2025 with a solid return to profit growth, driven by stronger premium tire sales, improving raw material costs and the early benefits of its North American restructuring. In the Sumitomo Q3 results, the company reported volumes are soft, but margins and mix are trending in the right direction. The company also reported a ramping up of its DUNLOP expansion strategy in North America, Europe and Australia.
From July through September, Sumitomo reported ¥289.4 billion (approximately $1.96 billion USD) in sales revenue, slightly above last year’s level. Business profit rose to ¥20.2 billion (approximately $136 million USD), a 5% increase year-over-year. Operating profit reached ¥19.1 billion (approximately $129 million USD), compared to a large loss in the same quarter last year. Profit attributable to owners of parent totaled ¥11.6 billion (approximately $78.4 million USD) after a ¥34.7 billion loss a year ago.
Across the first nine months of the year, cumulative sales revenue reached ¥861.6 billion (approximately $5.82 billion USD), down 1.5%. But operating profit climbed to ¥46.1 billion (approximately $312 million USD), more than tripling year-over-year due to the absence of last year’s North American restructuring charges. Profit attributable to owners of parent totaled ¥26.0 billion (approximately $176 million USD), up more than fivefold from 2024.
Tire Unit Volume Soft, Premium Mix Improving
The tire segment delivered ¥740.2 billion (approximately $5.00 billion USD) in sales revenue for the nine-month period, down slightly year-over-year. Business profit fell to ¥40.9 billion (approximately $276 million USD), reflecting lower OE and replacement volumes in Asia and North America, ongoing weakness in China, and a strategic reduction in low-margin products.
Still, the July-September quarter marked a turning point for Sumitomo. The company said its premium tire sales performed well in Japan, North America, and Europe. In Europe, stronger winter and all-season demand, plus successful price increases, helped the region return to profitability in Q3. In North America, structural reforms, including the closure of a high-cost U.S. plant, improved profitability even as tariff-related price hikes dampened volume.
Overall, July-September tire volume totaled 24.21 million tires, or 93% of last year’s level. For the full year, Sumitomo expects worldwide tire sales of 97.77 million units, about 5% lower than last year. Regional expectations include 88% of prior-year volume in North America and 99% in Europe.
Tariffs: Impact Easing, Strategy Adjusting
Sumitomo now expects the U.S. tariff impact for 2025 to total ¥13 billion (approximately $87.8 million USD), an improvement from the previously expected ¥14.5 billion (approximately $98.0 million USD). Price increases and ongoing cost-reduction programs (particularly “Project ARK,” a cost-reduction project designed to offset major headwinds like U.S. tariff impacts, weaker volumes, and rising operating costs by systematically cutting costs across the business) continue to soften the blow. ARK has already delivered ¥2.4 billion (approximately $16.2 million USD) in savings toward a ¥3.0 billion (approximately $20.3 million USD) 2025 target.
DUNLOP Expansion Takes Center Stage
One of the biggest developments for tire dealers in the Sumitomo Q3 results is the global expansion of the DUNLOP brand.
After acquiring DUNLOP trademark rights for Europe, North America, and Oceania earlier this year, Sumitomo began launching new DUNLOP products in the U.S. and Australia and will begin European sales in January 2026. The company plans to expand the North American lineup next year and says it is positioning DUNLOP as a global premium brand supported by expanded R&D in Europe and a product strategy centered on all-season and all-weather performance.
