Dr William V Mars, PhD, PE, received the Herzlich Medal recently at the International Tire Exhibit and Conference (ITEC), the largest tyre manufacturing trade show and conference in North America.
The award is bestowed every alternate year to recognise a tyre industry pioneer whose career and accomplishments have improved the industry, lasting impacting tyre design, development and manufacturing.
Receiving this medal is a pinnacle point in Dr Mars’ lifetime quest to improve how rubber products are designed and brought to market.
Dr Mars is an international leader in the failure mechanics of rubber, and his career has focused on applying experimental and computational mechanics in pursuit of better-performing rubber products. He is the author of the Endurica fatigue life solver – the world’s first commercially available and most highly-validated simulation for fatigue analysis of rubber.
He is the founder and president of Endurica LLC, a firm whose solutions are used by 13 of the top 20 global rubber product producers.
Dr Mars has over 30 years of experience developing testing and simulation methods in the rubber industry, including 16 years at Cooper Tire & Rubber Company. He earned his Honors BSME with Polymer Specialisation at the University of Akron and his MS and PhD degrees at the University of Toledo. He has also served as the Chief Editor of both Rubber Chemistry and Technology and Tire Science and Technology. He has over 60 peer-reviewed scientific publications and four patents in elastomer durability.
Medal presenter Bruce Meyer, Editor of Rubber News, noted his relationship with Harold Herzlich, whose career spanned decades in the tyre industry, decades more as an expert in tyre forensic cases and more than a couple additional decades as Technical Editor of Rubber & Plastics News.
Herzlich served as the Founding Conference Chairman for ITEC and 10 subsequent ITEC conferences. “I worked with Harold for many years,” explained Meyer. “He truly was one of the good guys of the tyre industry. And that’s appropriate, because today we are honouring Will Mars, Founder and President of Endurica LLC. And I can say definitively that Will also is one of the good guys in our industry.”
“Harold Herzlich himself is retired, (but) he did serve on the committee tasked with choosing a winner from among the highly qualified nominees. I asked him to send along a message for me to share, and this is what he had to say: ‘‘Even though I had very limited contact with Will, I, like many technical people in the industry, was aware of, and depended upon, his very capable and generous contributions as Editor to the Rubber Division’s highly regarded Rubber Chemistry and Technology. Will went beyond his publication activities and contributed actual hardware and software capabilities that are already accelerating the industry’s innovation process worldwide.”
Key impacts of William V Mars’ career on the tyre industry: • Pioneered Critical Plane Analysis that enables accurate tyre life prediction under complex loads. • Explained the phenomenon of improvement in fatigue life of the sidewall compounds in inflated tyres (strain crystallisation). • Expanded Futamura’s deformation index to predict tradeoffs between stiffness, mode of control and durability. • Developed incremental calculation method for elastomer fatigue analysis, enabling the simulation of multi-step durability tests, including FMVSS and high-speed protocols for tyres. • Developed rapid test method to determine the long-term durability of rubber. The method reduces testing time from weeks (or months) to under one hour and is based on intrinsic strength/fatigue limit physics. • Introduced fatigue crack growth testing protocols that produce more reliable data relative to prior methods. • Current market adoption: 13 of the top 20 global rubber product producers are using Endurica methods today.

- September 18, 2026
Michelin has unveiled the X Multi Energy D2 tyre, developed to address the specific challenges of regional haul operations. Fleets in this segment face demanding roads, frequent stop-and-start cycles and escalating fuel expenses that affect both performance and profitability. By blending durability, fuel savings and Michelin’s established performance standards, the new tyre aims to boost fleet productivity while reducing overall operating costs.
The tyre features a revised tread pattern and a new tread compound to better resist tread damage caused by high-torque vehicles and stop-and-go regional driving. It is constructed on Michelin’s Duracore casing, which integrates Infinicoil and Powercoil technologies and benefits from a reinforced bead design known as Duracoil Technology. This casing is engineered to last up to one million miles and support as many as four retreads.

In the effort to curb fuel expenses, the X Multi Energy D2 improves rolling resistance by 9 percent over its predecessor, the Michelin X Multi Energy D tyre, and by 18 percent compared with leading competitors. It also enhances late-life traction, offering 10 percent better wet handling and 16 percent better snow starting traction when worn, giving drivers and operations managers greater confidence on varying roads.

For original equipment manufacturers, the tyre meets Greenhouse Gas standards and supports applicable vehicle carbon-reduction requirements. Designed for regional applications where traction, durability and fuel efficiency matter, it is available in 295/75R22.5 LRG and 11R22.5 LRG and LRH sizes, replacing the X Multi Energy D tyre in those sizes.
Yahn Heurlin, VP of B2B Marketing, Michelin North America, Inc., said, “Michelin is driven by a deep commitment to understanding the needs and challenges customers face every day. This customer-first mindset inspires the development of purpose-built solutions designed to address real-world pain points and help fleets operate more efficiently.”
Firestone Launches Destination LE4 Highway Touring Tyre

- September 18, 2026
Firestone, a Bridgestone Americas subsidiary, has unveiled the Destination LE4 highway touring tyre as the successor to its best-selling Destination LE3. The new model features a deeper tread depth, an advanced compound and a non-directional tread pattern, delivering longer wear life along with improved wet and light snow performance for year-round driving confidence.
Backed by a 70,000-mile limited warranty, the Destination LE4 is projected in external testing to wear 16 percent longer than its predecessor, 9 percent longer than the General Grabber H/T and 43 percent longer than the BFGoodrich Advantage Control HT. Thinner 3D sipes enhance traction and handling, while internal testing showed wet stopping distances reduced by 8 feet versus the Toyo Open Country H/T II and 4 feet versus the BFGoodrich Advantage Ctrl HT, with dry stopping improved by 8 feet and 2 feet, respectively, plus a 2-foot dry gain over the LE3.

Sustainability gains come through wear-resistance technology, optimised material usage that lowers raw material consumption and enhanced traction technology. Two technical firsts originated at the Bridgestone Americas Technology Center in Akron, Ohio: a high-strength, lightweight carcass architecture using light body plies and steel cords for durability and low rolling resistance despite deeper tread, and advanced compound mixing that improves ingredient consistency for tread wear, handling and wet grip.
Available in 65 sizes for 15- to 22-inch rims, the Destination LE4 covers small CUVs, SUVs, pickups and larger trucks, including the Mazda CX-5, Ford F-150, RAM 1500, Chevrolet Trailblazer and Nissan Armada.
Jeremy Norwood, Chief Engineer, New Product Engineering, Bridgestone Americas, said, “Drivers loved the Firestone Destination LE3 for its comfortable, quiet ride and all-season reliability. With the new Destination LE4, we enhanced those strengths by extending wear life and improving wet-weather handling, delivering dependable performance, confident control and everyday value.”
