The concluding day of 2026 F1 Pre-Season Testing at the Bahrain International Circuit saw Charles Leclerc set the overall fastest lap of the entire six-day programme. The Ferrari driver delivered a time of 1:31.992s on the C4 compound Pirelli tyres during the final hour of running, improving by eight-tenths of a second on the previous benchmark established by Kimi Antonelli. This performance placed him ahead of Lando Norris in the McLaren, who recorded a 1:32.871s on the C3 tyre. Max Verstappen and George Russell followed, with times of 1:33.109s and 1:33.197s, respectively, both also set on the C3 compound. Notably, none surpassed Leclerc's own leading time on that particular compound, a 1:32.655s. Pierre Gasly rounded out the top times, utilising the softest C5 tyres to post a 1:33.421s.

The C5 compound saw limited use on the final day, employed only by Alpine and Williams for short-run simulations. Aston Martin, despite having the tyre available, opted not to run it and instead completed just six laps on C3s before their session was curtailed. In contrast, teams focused on different aspects of performance. Gabriel Bortoleto and Arvin Lindblad set the pace on the harder C1 and C2 compounds, respectively. The day was also notable for the absence of several drivers, including Fernando Alonso, Lewis Hamilton and Alex Albon, who did not participate in any track action.

Beyond outright speed, teams dedicated significant effort to long-distance evaluation. Gabriel Bortoleto completed 25 laps on the C2 compound for Audi, while Esteban Ocon undertook 24 laps on C1s for Haas. Ocon was also the sole driver to run intermediate tyres, completing four laps to assess front wing behaviour. Over the entire six-day test, a total of 41,366 kilometres were covered across all 11 teams, a distance exceeding the Earth's circumference. The C3 compound proved the most popular, accounting for 61 percent of all laps. In total, 591 sets of slick tyres were utilised throughout the pre-season, with 326 of those deployed in the final three days alone.

Mario Isola, Pirelli’s Motorsport Director, said, “The radical changes introduced to the cars have inevitably shifted the teams’ focus towards power units and aerodynamics rather than tyres over the last few days. The final stages of testing are usually dedicated to optimising the car-tyre package, but it is clear some teams haven’t reached that point yet. Generally speaking, track feedback has been consistent with our simulation expectations. Drivers were able to gain confidence with the entire Pirelli range through both performance trials and long runs, even using the C4 and C5 compounds which aren’t particularly suited to a circuit like Sakhir.

“Mechanical resistance appeared strong across all options, with no signs of graining or blistering. Degradation levels are almost certainly higher now than what we expect for the Bahrain race, when temperatures will be lower and cars more developed. A central theme this season will certainly be balancing temperatures between the axles, especially ahead of the first race in Melbourne. The lower loads of a street circuit might require more intensive tyre preparation or differentiated tyre blanket temperatures, particularly in qualifying. In any case, it will be interesting to discover in Australia how much teams have been ‘sandbagging’ their engine power to avoid showing their hand. We only have to wait a couple of weeks to see the true pecking order.”

Kuraray America, Inc. marked National STEM Day on 8 November by spotlighting a community educational event that brought together 15 of its volunteers and students from the Houston Japanese Supplementary School at San Jacinto College for a day of hands-on exploration and discovery.

Participants engaged in activities illustrating how science, technology, engineering and mathematics (STEM) converge in chemical manufacturing. Experiments with superabsorbent polymer beads explored chemistry and material properties, while a tour of the college’s facilities introduced industrial equipment. Students also learned about water filtration and distillation processes and how mathematical concepts underpin scientific and engineering applications.

One student showed particular interest in the distillation tower, linking the experience to the Kuraray Group’s contributions to everyday life and its mission of achieving for people and the planet what no one else can. The event also benefited KAI volunteers, who shared technical knowledge, exchanged perspectives and learned alongside potential future scientists and engineers.

Kuraray America thanked Reiko Fuwa and Tomohiro Tani for coordinating the visit, Hans Vandommele for sharing his expertise and all 15 KAI volunteers. The company also expressed appreciation to San Jacinto College for facility access and to the Houston Japanese Supplementary School students for their curiosity, enthusiasm and thoughtful questions.

Liberty Tire Recycling attended the 2026 SEMA Show in Las Vegas, held from 3–6 November at the Las Vegas Convention Center. The automotive aftermarket event, one of the industry's largest, drew over 160,000 attendees from the automotive, tyre and transportation sectors to review new products, technologies and business opportunities.

The Lakin Tire brand, a consistent SEMA exhibitor, once again used the show to reinforce industry relationships and present Liberty's tyre collection, recycling and sustainable resource management capabilities. Personnel from Grade/Used Tires, Commercial Truck Tires, Metals, Recycling and Collection, together with corporate and regional leadership, met customers, suppliers and industry professionals from around the world.

The booth received existing and prospective customers from numerous tyre and automotive segments during the week. Costco Wholesale Corporate Office, United Tires and UTU Wholesale were among the organisations that stopped by to examine Liberty Tire's products, services and nationwide reach. The company viewed the event as an effective forum for monitoring emerging market trends and demonstrating its position in recycling and sustainability, alongside its focus on innovation, workforce development and circular economy principles.

A memorable moment came when a high school shop teacher and students, attending through a special educator programme, toured the booth to learn about tyre recycling and industry operations. Liberty team members provided industry insights, outlined career pathways and acknowledged educators' contribution to developing future skilled trades professionals, supplying tyre inflation gauges for classroom use.

Laufenn, Hankook's associate brand, earned a ‘Good’ ratingwith an overall score of 2.2 for its G Fit 4S in the Auto Bild Allrad all-season SUV tyre test published on 8 October 2026 (issue 41). The tyre competed credibly against 11 rivals from established premium marques, finishing competitively in a 12-strong field.

Wet handling proved a particular strength, with the G Fit 4S collecting the second-highest rating shared with other models. Aquaplaning resistance also impressed, as the tyre held its line until stability began to fade at roughly 100 kmph (62 mph). In snow, it recorded the third-shortest braking distance, matching two other contenders.

Testing spanned snow, wet and dry disciplines, each weighted equally in the final ranking, with a third-generation MINI Countryman serving as the test vehicle. Snow assessments were carried out in New Zealand, while European venues hosted the wet and dry evaluations. The jury's conclusion underscored Laufenn's value-focused positioning, finding the G Fit 4S a solid option for cost-conscious buyers.

Tyres Europe has underscored that tyres qualify as fully recyclable under ISO 22628:2002 and UN Regulation No. 133, describing the established methodology as a robust foundation for assessing tyre recyclability. The organisation recently set out its position on the matter.

The distinction between recyclability and actual recycling rates is central to the group's argument. Recyclability refers to the technical potential of a product and its materials to be recycled, while the real rate hinges on treatment capacity and demand for secondary raw materials. Regulatory frameworks should therefore separate the two concepts clearly and align with an internationally recognised standard.

Tyres consist of rubber compounds, chemical additives and reinforcing textile and steel cords, and at end of life they are separated into rubber, textile and steel fractions, all of which existing mechanical or chemical routes can recycle. Mechanical processing yields rubber granules and powders usable as secondary raw materials across many applications, recovered textiles can be further processed and valorised, and cleaned recovered steel can re-enter metal recycling and steelmaking.

Tyres Europe pledged continued cooperation with policymakers and value-chain partners to strengthen circularity and maximise recovery of valuable tyre materials in Europe, with the full paper available on its website.
