Bridgestone has been selected by Mercedes-Benz AG as the development partner for tyres for its technology programme, the Mercedes-Benz VISION EQXX. The futuristic electric vehicle (EV) is the car manufacturer’s answer to making EVs more efficient and increasing electric range to a new level. Bridgestone said in a statement that its engineers collaborated with Mercedes-Benz to create custom-designed tyres that have contributed to increasing the vehicle’s efficiency and thus driving range to a real-world 1,000km – from Sindelfingen, Germany to Cassis, France – on a single charge. 

Bridgestone designed bespoke Turanza Eco tyres that combine its proprietary and lightweight ENLITEN Technology to reduce tyre rolling resistance and weight by up to 20 per cent, along with its ologic technology designed to enhance battery range by means of a large tyre diameter to reduce rolling resistance, and a narrow tyre width to reduce aerodynamic resistance. 

In collaboration with Mercedes-Benz’s aerodynamic department, the tyre also comes with optimised sidewalls and a bead area design that match the covers mounted on the 20-inch, forged-magnesium wheels, greatly improving the tyre’s aerodynamics.  

Emilio Tiberio, COO & CTO at Bridgestone EMIA, said: "As part of our commitment to help shape a sustainable future of mobility, Bridgestone is proud to have co-developed with its long-term partner the right tyres for a project as innovative as this. The Mercedes-Benz VISION EQXX is a project that is totally aligned with our own EV ambitions and targets, especially as we are investing to make electric mobility more efficient and accessible through a fully integrated approach. This includes pioneering premium tyres and tyre technologies able to tackle the greatest EV challenges. This is especially true as we heavily invest in EV tyre development – currently allocated over 30 per cent of our R&D resources – and improve upon our technologies in 2022.” 

The tyres were developed using Bridgestone’s virtual tyre modelling and simulation capabilities, which enable a digital version of an in-development tyre to be created and tested. Using this technology means that development time was cut considerably. 

Bridgestone leveraged the virtual environment for a large part of the development process, enabling prediction of how the tyre would perform in different conditions before physically building it. The increased flexibility offered by virtual tyre development enables Bridgestone to test far more variants of a given tyre, thanks to the speed at which modifying a tyre’s digital twin and immediately testing it can take place. Additionally, this virtual tyre development delivers multiple environmental benefits, as both natural resource use and exhaust emissions are cut, thanks to a lower number of prototypes that need to be produced and tested, the release added.

Yokohama Rubber Co., Ltd. said it has begun supplying its BluEarth-Es ES32 tyres as original equipment to Suzuki Motor Corporation for the Wagon R mini-vehicle, following the model’s launch in Japan in December 2025 after a minor update.

The Wagon R is fitted with 165/55R15 75V tyres.

BluEarth-Es ES32 is a standard tyre under the BluEarth YOKOHAMA global tyre brand, developed around the concept of being “environmentally, human, and socially friendly”. The tyre combines fuel efficiency with extended service life by reducing uneven wear. For the Wagon R, Yokohama Rubber said the tyres use tread patterns and compounds designed to deliver both lower rolling resistance and improved wear resistance.

Suzuki’s updated Wagon R incorporates additional safety features, including the Dual Sensor Brake Support II collision-mitigation braking system. The vehicle is also designed to offer a quiet and comfortable ride, stable steering and a refined exterior.

Yokohama Rubber said it continues to develop tyres using its BluEarth technology, with a growing number of these products being factory-fitted on petrol-powered vehicles, hybrid models and electric vehicles across a range of segments.

Yokohama Rubber Co., Ltd. said it has begun supplying its ADVAN Sport ZPS tyres as original equipment to Toyota Motor Corporation for the new GR Yaris, following the model’s launch in the Middle East in December 2025.

The tyre supplied is sized 225/40RF18 88Y.

ADVAN Sport ZPS is derived from the ADVAN Sport, the high-performance tyre in Yokohama Rubber’s global flagship ADVAN brand. It is a run-flat tyre with reinforced sidewalls designed to support the vehicle even in a zero-pressure condition, such as after a puncture. The company said the tyre balances ultra-high-speed handling with wet performance, quietness and comfort.

Yokohama Rubber tyres are already fitted to several models in Toyota’s GR sports car range. In recent years, the company has supplied ADVAN APEX V601 tyres for the GR Corolla and ADVAN FLEVA V701 tyres for the Corolla Cross GR Sport.

The supply forms part of Yokohama Rubber’s three-year medium-term management plan, Yokohama Transformation 2026, covering 2024 to 2026. Under the plan, the consumer tyre business is seeking to increase the proportion of high value-added products, with a focus on expanding original equipment supply of ADVAN tyres and GEOLANDAR tyres for SUVs and pick-up trucks.

The Yokohama Rubber Co., Ltd. has been selected by Toyota to provide its ADVAN V61 tyres as original equipment for the newly launched global hybrid SUV, the RAV4. The tyres, fitted specifically to the Z and ADVENTURE trim levels, come in the sizes 235/65R17 and 235/60R18. This partnership follows the worldwide introduction of the ADVAN V61 in March 2025, a premium summer tyre designed for sport utility vehicles that is now available in all markets except North America.

As part of Yokohama’s flagship ADVAN line, the V61 is engineered to deliver the brand’s signature high performance. It achieves a careful balance between fuel efficiency, stable handling and reduced noise, aiming to provide comfort for both daily urban use and extended journeys in heavier SUVs. The model is already supplied as original equipment on several premium vehicles and is offered in a broad selection of sizes for the aftermarket.

The development of these tyres was supported by Yokohama Rubber’s proprietary HAICoLab, an artificial intelligence framework. This system combines human innovation with the extensive data-processing power of AI to accelerate discovery and foster digital advancements in tyre technology.
