Pirelli SCX Supersoft Powers Record-Breaking Qualifying And Race Victory For Bulega At Assen
- By TT News
- April 20, 2026
Pirelli has reported a dominant all-Ducati podium in Race 1 of the Dutch Round at Assen, the third fixture of the FIM Superbike World Championship. Nicolò Bulega extended his perfect start to the season with a seventh consecutive victory after a close contest with team-mate Iker Lecuona, who settled for second. Sam Lowes finished third, completing the manufacturer’s sweep. All three riders selected SC1 soft compound tyres for the front axle and SC0 soft rubber at the rear.
The weekend also highlighted the speed of Pirelli’s softest tyre options despite relatively cool conditions. During qualifying, Bulega established a new Assen lap record using the SCX supersoft rear, clocking 1 minute 32.144 seconds. That time shaved nearly half a second off the previous benchmark of 1’32.596, set by Lowes the prior year with the SCQ extrasoft compound. The other two Ducati riders on the front row, Lowes and Lecuona, also eclipsed the old record.
Elsewhere at the Dutch circuit, Jaume Masia won WorldSSP Race 1 on a Ducati, followed by Albert Arenas on a Yamaha and Tom Booth-Amos on a Triumph. Most of the Supersport field, including the top two, ran the SCX supersoft rear, while the third-place rider and nine others used the soft SC0; the SC1 was the universal front choice. In World Sportbike action, local rider Jeffrey Buis triumphed on a Suzuki, and the WorldWCR race went to Spain’s Maria Herrera on a Yamaha for her second win of the season. Both support classes employed DIABLO Superbike tyres with SC1 compound front and rear. Over the first two days, track temperatures varied from 16 degrees Celsius during early Superbike practice to 24 degrees for Supersport Race 1.



Giorgio Barbier, Pirelli Motorcycle Racing Director, said, “Despite the low temperatures, typical of Assen at this time of year, soft tyres were used in both WorldSBK and WorldSSP. The development work Pirelli has carried out over the years has enabled us to improve versatility and widen the operating temperature window of our tyres. As a result, the soft compounds were used with track temperatures slightly over 20 °C, delivering excellent performance. The new SCX supersoft tyre range, already used last year as development specification E0126, allowed Bulega in qualifying to improve the 2025 lap record by almost half a second, which was set with an even softer compound, the SCQ extrasoft. The SC0, on the other hand, starred in Race1: given the rather low temperatures, the riders preferred an already well-established solution to the development alternative F0298.
“In WorldSSP, both rear options – SCX and SC0 – proved equally competitive, as confirmed by the choices made by the riders on the podium.
“At the front, in both classes, the choice was unanimous: SC1, which ensures good grip and stability. For tomorrow’s Superpole Race, in dry conditions, we expect the SCX supersoft to be used at the rear, as it is more competitive over the 10-lap distance thanks to the extra grip compared to the SC0.”

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 G Fit 4S Earns ‘Good’ Rating In Auto Bild Allrad All-Season SUV Tyre Test

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 Backs International Standards As Basis For Tyre Recyclability Assessment
- By TT News
- November 12, 2026
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.
