Apollo Vredestein released updated versions of its high-performance summer tyre ranges for premium SUVs, high performance cars and sportscars.

Optimised for larger wheels (18- to 22-inches), the Ultrac Vorti+ and Ultrac Vorti R+ tyres feature new construction and revised compound materials to deliver outstanding performance in wet and dry conditions, as well as improved efficiency.

The Ultrac Vorti+ offers drivers superior levels of control, even at the limit of grip. Compared with its predecessor, the Ultrac Vorti, the new tyre has stiffer shoulder construction and sidewalls and a 13% larger bead area. New high-traction tread compounds have been introduced to improve grip and reduce braking distances in both wet and dry conditions. Combined, the changes deliver greater precision and response while cornering and a 5%* improvement in dry handling.

The Ultrac Vorti R+ provides an even higher level of control, especially at greater speeds and during harder cornering. Direct and predictable steering precision coupled with superb handling capability is achieved through the significantly larger apex base, stiffer sidewall construction, and the stable centre rib. In addition, the high traction tread compound is a carefully balanced new performance-centric polymer and resin mix, which enhances grip and control under braking and during rapid direction changes.

For both the Ultrac Vorti+ and Ultrac Vorti R+ the use of next-generation body compounds – in the apex area, rim cushion and carcass – have been deployed to reduce rolling resistance, helping to lower fuel consumption and extend the tyre’s life.

The new Vorti+ range is available in sizes from 18 to 22 inch, while the Vorti R+ is available in 19 to 21 inch. Some of the available sizes have been optimised for rear-axle use and are designed with wider belt angle for even better stability. All variants feature circumferential grooves for efficient water drainage on wet roads, meaning superior wet handling and optimal aquaplaning prevention.

Both of the Ultrac Vorti+ and Ultrac Vorti R+ ranges have been developed and produced at Apollo Vredestein’s R&D facilities in Enschede in the Netherlands.

Yves Pouliquen, Sales and Marketing Director, Europe at Apollo Vredestein, said: “Vredestein tyres already have a long-standing reputation within the high-performance segment, and we are building upon that with the launch of the new Ultrac Vorti+ and Vorti R+. Offering improved standards of performance and safety, and with all-wheel drive and rear-wheel drive versions, these new tyres are engineered for enthusiast drivers and for the most demanding dynamic situations.”

The new Vorti+ tyres recently made their debut on the striking Ferrari ‘Breadvan Hommage’ – a coach-built car styled by Niels van Roij Design in the Netherlands. “Extraordinary looking vehicles must be extraordinary to drive, and tyres have a key role to play in this,” comments Niels van Roij. “That is why I insist on fitting ultimate performance tyres that meet premium quality standards and have an exquisite aesthetic. The fact that Vredestein tyres like the Ultrac Vorti+ were developed together with ItalDesign ensures the perfect marriage of Dutch tyre-manufacturing heritage and inimitable Italian flair.”

The project, developed in partnership with Goodyear Tire & Rubber, represents a significant improvement over conventional metal spring tyre.

NASA has completed testing of revolutionary shape-memory tyres for Mars rovers, marking a significant advance in technology for future Red Planet exploration.

The testing, conducted at Airbus Defence and Space in Stevenage, United Kingdom, evaluated new tyres made from nickel-titanium shape memory alloys (SMAs) — metals that can return to their original shape after being bent, stretched, heated and cooled.

While NASA has explored only one percent of the Martian surface, these innovative tyres could help future missions more effectively navigate the planet's challenging, rocky terrain.

The breakthrough emerged from a chance encounter between NASA scientists at the Glenn Research Center in Cleveland.

"The minute I saw the tyre, I said, aren't you having problems with that plasticizing?" said Dr Santo Padula II, materials research engineer at NASA Glenn. "Colin told me, 'That's the only problem we can't solve.' I said, I have your solution. I'm developing a new alloy that will solve that. And that's how SMA tyres started."

The fall 2024 tests at Airbus's Mars Yard — a facility simulating Martian conditions — demonstrated the tyres' capabilities on simulated terrain.

"We went out there with the team, we brought our motion tracking system and did different tests uphill and back downhill," said Colin Creager, a mechanical engineer at NASA Glenn. "We conducted a lot of cross slope tests over rocks and sand where the focus was on understanding stability because this was something we had never tested before."

The project, developed in partnership with Goodyear Tire & Rubber, represents a significant improvement over conventional metal spring tyre. The new alloy can withstand extreme stress while maintaining its original shape.

Looking ahead, NASA plans to expand the technology's applications. "My goal is to extend the operating temperature capability of SMAs for applications like tires, and to look at applying these materials for habitat protection," Padula said.

The research could benefit both Mars and lunar missions, potentially protecting habitats from micrometeorite strikes and enabling long-term human presence on both celestial bodies.

The Yokohama Rubber Co., Ltd., has commenced the practical testing of a technology that uses artificial intelligence (AI) to gauge air pressure from the sound made by tapping truck and bus tyres.

In collaboration with METRIKA, Inc., Yokohama Rubber is creating an artificial intelligence algorithm that can detect the sounds produced by tapping the tyre from a range of ambient noises, ascertain the sound interval – the time and duration of the sound – and calculate the tyre's air pressure based on the sound. Furthermore, METRIKA and Yokohama Rubber have created a specialised application prototype and are presently carrying out real-world testing at a business involved in transportation. By capturing the sound produced while tapping the tyre on a smartphone app, this technology will allow drivers to visually understand the tyre's air pressure and whether additional pressure is required. Anyone will be able to do a very accurate air-pressure check thanks to this technology, eliminating the requirement for a special device or any special skill.

The practical testing will be used by Yokohama Rubber to enhance the application's useability and the AI algorithm's accuracy. Furthermore, Yokohama Rubber intends to integrate this new technology into its in-house next-generation Tyre Management System (TMS), which leverages the Internet of Things (IoT) to suggest suitable goods and business strategies for organisations involved in transportation.

The Goodyear Tire & Rubber Company and TNO have successfully demonstrated that the integration of tyre intelligence technology into the automatic emergency braking (AEB) system of a vehicle has the potential to mitigate crashes even in challenging road conditions.

According to recent wet road testing, an improved AEB system with Goodyear SightLine technology may help reduce collisions at up to 80 kmph (50 mph) by applying brakes early. All things considered, the combination of AEB and SightLine insights on tyre and road condition data contributes to reliable performance in a variety of situations. This follows Goodyear and TNO's successful CES 2024 demonstration of tyre intelligence integration with antilock braking systems (ABS).

The automotive industry has placed a lot of emphasis on the AEB system, which applies the brakes automatically when a collision is about to occur in order to assist prevent or lessen the severity of crashes. The AEB system can work more efficiently in a variety of driving conditions, including low-friction surfaces like wet roads or ice, by integrating Goodyear SightLine, the company's suite of tyre intelligence solutions. Currently, existing systems are usually tuned for high-friction surfaces like dry asphalt. Tyre intelligence may give the AEB more detailed information about the real tyre and road conditions through the contact patch with the road, allowing for more intelligent and accurate decision-making.

Chris Helsel, Senior Vice President and Chief Technology Officer, Goodyear, said, "Safety is a cornerstone of Goodyear's commitment to innovation. By providing critical inputs about tyre and road conditions into AEB systems, we are helping OEMs and their customers take a leap forward in safety, well ahead of the National Highway Traffic Safety Administration's (NHTSA) 2029 mandate for AEB systems in passenger vehicles. Beyond this mandate, AEB systems will play a critical role in automated driving, helping to provide a comprehensive safety solution at all times."

Martijn Stamm, Marketing Director, Unit Mobility & Built Environment, TNO, said, "TNO is dedicated to enhancing the safety, efficiency and sustainability of vehicles. Our collaboration with Goodyear aims to predict the braking distance of a vehicle in more conditions, like dry and wet asphalt, and trigger the AEB timely to reduce accidents and ultimately safe lives. This knowledge is a key enabler for a safe introduction of higher levels of automation."
