Bridgestone Expands VT-TRACTOR Line With Six New XXL Sizes For High-Horsepower Tractors
- By TT News
- May 05, 2026
Bridgestone is broadening its premium agricultural tyre portfolio for next-generation high-horsepower tractors. The company has added six extra-large sizes to its VT-TRACTOR range, covering 38-to-46-inch rims. These XXL tyres deliver superior traction, extended wear life and enhanced durability. An optimised rolling circumference ensures ideal lead percentage between front and rear tyre combinations, which is critical for maintaining proper driveline synchronisation and preventing mechanical stress under heavy field loads.
Advanced design features enable these performance gains. Developed using virtual three-dimensional simulation and robust Bridgestone design criteria, the tyres incorporate deeper and wider tread profiles that balance traction with even wear distribution. A patented involute lug design provides up to 12 percent more lug volume than competitors, maximising grip while minimising energy loss. This design maintains consistent performance over extended working seasons, reducing the need for premature replacements and lowering operating costs for farmers.
Durability comes from Bridgestone’s unique S-LINE bead profile, offering greater flexibility at lower pressures to reduce soil compaction and prevent rim slip. The high durability casing ensures even pressure distribution across the soil footprint, preventing both circumferential and shoulder cracks while improving tyre longevity. The tyres are fully compatible with Central Tyre Inflation Systems, allowing operators to adjust pressure on the move for different applications. Additional benefits include improved fuel efficiency and stable steering precision even under challenging field conditions.
Production takes place at Bridgestone’s Puente San Miguel plant in Spain, following significant upgrades to manufacturing capabilities including advanced production technology and specialised equipment for large-diameter tyres. These investments enable expansion into the 44- and 46-inch segment. The new XXL sizes will launch progressively from April 2026, expanding compatibility with a wider range of modern high-horsepower agricultural machinery across global markets.
Andrea Marconcini, Director Agriculture at Bridgestone EMEA, said, “Today, farmers operate larger, more powerful tractors and need tyres that can keep up – doing more and going further in demanding conditions. Our updated VT-TRACTOR range is engineered to enable faster, more efficient work in the field, together with a longer service life that reduces long-term costs.”
Kuraray America Marks National STEM Day With San Jacinto College Event

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 Showcases Recycling Leadership At SEMA 2026

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.
