Continental has launched three all-new MTB tyres in order to give riders better performance, longevity and maximum grip on any terrain. Every rider, from XC racers to trail fans, will find the ideal tyre for their preferred terrain thanks to the addition of the new Dubnital, Trinotal and Magnotal tyres to the well-known Gravity line.

Dubnital is designed for dry to moist environments and is best suited for rocky, hardpack and medium-loose soils. It is designed to fulfil the demands of XC and downhill riders seeking maximum speed. Dubnital, a direct successor to the 'Race King', offers unrivalled efficiency, grip and control at high speeds thanks to its cutting-edge tread and innovative rubber compositions. Trinotal, which replaces the popular 'Cross King', is meant to be versatile and perform well in both dry and wet circumstances. The tyre is designed for XC and downhill riders and provides excellent grip and stability, helping them to easily tackle a range of terrains. The all-rounder Magnotal, which replaces the 'Mountain King', is designed for aggressive all-mountain and trail riders and strikes the ideal mix of performance and control. It thrives. Magnotal provides excellent grip for riders in dry to wet situations, tackling hard, loose and muddy soils with ease.

Alexander Haenke, Product Manager – MTB & Gravel, Continental Tires, said: “With the introduction of Dubnital, Trinotal and Magnotal, we are proud to complete the overhaul of our MTB lineup, finally replacing our iconic 'Kings’. The new models now seamlessly fit into the nomenclature and logic of our Gravity range tyres, and give riders the freedom to use our portfolio as a playground to create their perfect setup. We’ve tested these tyres with gold-medal-winning athletes to ensure they perform at the highest level – now it’s your turn to push their limits. While our technology has already been proven in the world of gravity, we’re excited to see how riders take them to new heights across other disciplines”.

German chemical group WACKER has announced a price increase of up to 15 percent for its resins, dispersions and dispersible polymer powders produced at its European and US facilities. The adjustment takes effect on 1 June 2026, or as existing customer contracts permit. The move is designed to allow the company’s Polymers division to maintain high product quality, deliver technological innovations and provide superior customer service and technical support. It will also support investments aimed at securing future growth in key markets.

Rising costs for raw materials and logistics have forced the pricing measure, with the Polymers division being particularly affected. The recent conflict in the Middle East has caused significant disruptions across global commodity markets. As a direct result, prices for energy, raw materials and transportation have climbed sharply.

Despite the increase, WACKER remains focused on sustaining its commitment to customer support and long-term capability. The company underscored that the adjustment is necessary to continue meeting market demands while ensuring operational stability and future-oriented development across its focus markets.

Pirelli North America has launched its first closed-loop circular recycling initiative, marking a significant step in the company’s broader strategy to increase recycled and bio‑based content in its tyre production. The project has received the Tire Recycling Foundation’s Value Chain Collaboration Award.

The programme recovers scrap tyres generated during Pirelli’s own North American manufacturing process. These materials are sent to Bolder Industries, which applies ISCC PLUS‑certified pyrolysis technology to produce BolderBlack recovered carbon black. Pirelli then reintroduces this material into new tyre production at its North American facilities, partially replacing virgin carbon black. The effort is part of a wider Pirelli plan to expand such industrial ecosystems across the group’s production network, aiming to valorise waste by reintegrating recovered materials into tyre manufacturing.

Beyond the award, the initiative reflects Pirelli’s broader circularity approach, which includes ongoing work to boost recycled and bio‑based material usage. The company targets over 80 percent bio‑based and recycled content in its best‑performing products and forty percent in total production by 2030.

Claudio Zanardo, CEO, Pirelli North America, said, "The Rome plant is one of the most technologically advanced manufacturing facilities in Pirelli. This initiative reflects an approach focused on increasing the use of recovered materials within existing production processes. It is part of a broader effort to gradually integrate raw materials derived from recycled resources into our products while maintaining consistency in performance and quality."

Tony Wibbeler, CEO, Bolder Industries, said, "Our collaboration demonstrates that a traceable, mass-balance approach to tyre-to-tyre circularity is not only achievable, but it's ready to scale inside a premium manufacturing environment, meeting real performance and certification requirements at every step. This is the kind of progress the industry has been working toward for many years."
