After years of engineering development and large-scale field testing, Global Air Cylinder Wheels (GACW), the Phoenix-based developer of the Air Suspension Wheel (ASW), has announced a key milestone in the transition from research and development to commercial deployment for 2026, following successful extreme-condition validation trials in Minnesota mining operations.

The recent winter trial subjected the company’s non-pneumatic mechanical wheel system to real-world operating conditions in Minnesota in December, with temperatures ranging from approximately -29°C to -40°C under full production loads and operational conditions. The testing focused on validating suspension performance, tread compounds, lubrication systems, and traction in extreme sub-zero mining conditions.

Goodyear and Citroën have partnered for the launch of the latter’s ELO concept. As part of this collaboration, Goodyear has developed the Eagle Xplore, a bespoke concept tire with features focused around tire connectivity and design.

The tire features an orange sidewall pigment in line with the vehicle’s signature color and also integrates Goodyear SightLine, an advanced suite of tire intelligence technologies, fully connected to the car and accessible via the cockpit and ELO’s app. For the first time, SightLine displays real-time tire pressure directly on the vehicle’s rim through an LED sidebar.

The Eagle Xplore’s tread pattern draws from Goodyear’s iconic Wrangler line, while the LED sidebar shows real-time information on tire pressure and load – green indicates optimal pressure, red signals that adjustment is needed.

Yangwang, BYD’s sub-brand, has set a global electric vehicle (EV) top-speed record of 472.41km/h at the ATP Automotive Testing Papenburg test track in Germany, using Giti Tires. The feat was achieved with Yangwang’s latest U9 Track Edition supercar on August 8, 2025.

The Yangwang U9 Track Edition is based on the e4 platform and DiSus-X core architecture.

The Track Edition’s e4 platform features a quad-motor system with 30,000rpm high-performance motors, each delivering 555kW of peak power. The combined output exceeds 3,000PS, enabling a power-to-weight ratio of 1,217PS per metric ton. The quad-motor independent torque-vectoring system continuously monitors road feedback, adjusting each wheel’s torque more than 100 times per second.

Marangoni has introduced its latest Ringtread Drive Regional (RDR) model, the RD3. Designed for fleets operating in regional markets, the RDR RD3 offers improved mileage and traction, and is 3PMSF certified.

The RDR RD3 features a robust, monodirectional tread design with asymmetric block angles that enhance grip and promote even wear. Its optimized profile aims to reduce stone retention, preserving the tire casing for future retreading cycles. Reinforced shoulder bridges provide lateral stability and prevent deformation under stress.

“With the RDR RD3, we’re bringing the next generation of performance and efficiency to the regional segment,” said Ronny Dietsch, sales and marketing director at Marangoni.

Bridgestone has signed an agreement to develop and supply tires for ispace‘s small and medium-size lunar rovers.

The tire maker has been developing soft, elastic lunar rover tires that can flexibly change shape in response to harsh surfaces, like those on the moon. These tires will be equipped on the lunar rover prototypes currently being developed by ispace.

Performance verification will be conducted on Earth ahead of use on the moon. Through these initiatives, both companies will assess the feasibility of the technologies and business opportunities on the lunar surface as they aim for the practical application of the tires as early as 2029.

Pirelli has launched the Scorpion XC RC and M 100% ‘Made in Italy’ mountain bike tires, which are manufactured at Pirelli’s Milan-Bollate plant with Forest Stewardship Council-certified natural rubber.

Made for cross-country races, the tires have been designed for the toughest competitions but can also be used for a wide range of other cross-country applications, including light trail riding.

Race compound

The Scorpion XC RC and M tires use the latest RACE Compound, developed by Pirelli technicians in the Motorsport Compound division, and represent Pirelli’s “pinnacle of off-road performance in the XC discipline”, according to the tire maker.

A pair of Kumho tire concepts have been honored with the iF Design Award. The Volume and the Origami were recognized for their future-oriented innovation. The Volume is a next-generation tire concept that dynamically adjusts its structure and functions according to speed and road conditions. The Origami is a folding tire designed specifically for outer space exploration and settlement construction. Boasting an innovative structure inspired by the art of paper folding, the tire maximizes mobility efficiency in space environments.

The concepts were developed through Kumho’s Technology Outsourcing program, a collaborative research project intended to develop tires for future mobility.

Goodyear brand Avon Tyres has expanded its WX7 winter tire range, increasing access to a broad spectrum of cars with 12 additional SKUs between 17in and 19in, bringing the total size of the range to 29 fitments.

WX7 is suitable for snow, ice, slush and wet conditions.

The center grooves are designed with serrated edges that trap the snow and provide an improved ‘snow-on-snow’ grip. A solid center rib aims to enhance handling and steering response on wet and icy roads.

Avon says that 3D micro-gauge siping technology provides improved braking performance across in wintry conditions.

An additional 17 Euro/hard metric sizes are scheduled to be added to Yokohama’s Geolandar X-AT extreme all-terrain tire range to pair with existing LT-metric sizes. By the end of 2023, 80 sizes to suit 15-22in rim diameters will be available for application to pickup trucks, jeeps and SUVs.

Yokohama has designed the Geolandar X-AT with dynamic, large shoulder blocks that vary in length to provide a biting edge and promote mud and stone ejection. When these are combined with the tire’s angular center blocks, added durability and grip are provided. Furthermore, zig-zag grooves on the tread interrupt airflow to reduce the amount of pattern and road noise.
