TIRED OF POOR TYRE KNOWLEDGE
- By Adam Gosling
- May 05, 2021
As I speak with industry members, regulators and legislators I continue to be stunned by the lack of appreciation of the very critical role that tyres play in our societies.
Governments bleat about fuel security “investing” precious currency to prop up petroleum fuel storage and production in the face of the ever-expanding development of electric vehicles and more recently the advent of hydrogen as a viable fuel with thanks to the PV (solar) industry advancements. Tyres? What do you mean tyres? Without tyres our societies would grind to a halt in the near term. How are they not a strategic consideration?
Our industries (tyre, road freight transport, mining, public transport and leisure) are facing sufficient difficulties with COVID as well as international shipping challenges to be faced with continued ignorance and negligence by our legislators and regulators.
Please review your countries legislative requirements in regards tyre inflation for light vehicles (say <4,500 kgs) and then the same requirement for heavy vehicles (>4,500 kgs). What do you find?
Mostly I think you will find that tyre inflation pressures are regulated for light vehicles via the vehicle manufacturers tyre placard. For heavy vehicles there is little, if any, such requirement. To illustrate the yawning gap between reality and regulation one peak heavy transport regulatory body published a procedure for roller brake testing for heavy vehicles. The procedure details in minute detail the requirements of the pneumatic system on the truck under test yet merely stated “tyres should be inflated.” As everyone in the tyre industry understands a tyre can be inflated at low pressures totally unrelated to actual operating pressures. What connects the brakes to the pavement? Tyres!
I’ve spoken at length about the absolute requirement for a tyre to be appropriately inflated. This is basic physics, the air molecules captured within the tyre’s air chamber actually support the applied loads. If there are insufficient molecules of air the tyre will be overworked so overheat and so enter a failure phase. There are other requirements for the inflation being the actual shaping of the tyre to interface with the pavement at the optimum level, read traction. A wide based tyre requires special construction to maintain the tread platform shape. If the inflation pressure is not at the manufacturer’s specified level will this critical shape be maintained? Then it is not only the performance of the tyre in question but also the safety of the vehicle and that of the general public in the areas this vehicle operates in.
The extensive report produced by the TNO Organisation (TNO 2013 R10986) detailed not only the exhaust emissions as a result of inappropriately inflated tyres but also the road safety outcomes. This paper is now just over eight years old but the situation with real time pressure monitoring for heavy vehicles remains as it was, 50 years or more ago. WHY? Are our regulators asleep at the wheel (or tyre some may say) through entrenched inaction and ignorance? Or is it that there are just “no votes” in tyres and everyone just ASSuMes their tyres are “ok”?

EV tyres
With the advent of electric vehicles, the ramifications for tyres are huge. In the past internal combustion engines (ICE) built up torque over a rev range, drivelines multiplied the torque developed and for heavy vehicles there is a sweet spot for torque. The multi speed gearboxes assisted the driver to maintain forward motion within this torque sweet spot. Electric motors apply maximum torque over most of their operating range. From the instant the power is applied by the driver (be that human or robotic) the tyres are under peak stress. Any deficiency within the tyre will be magnified with detrimental results. Such a deficiency may be of a manufacturing nature but this is largely controllable by the manufacturer. What is not currently controllable is the human maintenance factor, the applied inflation pressure.
Tyre manufacturers have for as long as they have been manufacturing tyres been informative about the criticality of appropriate tyre inflation. There are untold charts and pictorials showing how a tyre is influenced by under or over inflation yet our regulators and legislators continue to keep their heads buried deep out of the light. WHY when tyres are such a critical component of our modern-day motor vehicle? I would charge ignorance and negligence on one hand but then on the other suggest that because tyres work as well as they do, are as forgiving (by nature of their fundamental flexible design) our “guiding powers” can focus on other trendy and glamorous aspects such as stability control or autonomous braking. An important question for these people to consider and respond to; “what item on the vehicle transfers the power (and so directly influence these vehicle control systems) from the vehicle to the pavement (be that power tractive or retardation)? Yes of course, the humble tyre.
So, when a government sponsored or publicly funded body involved in road safety ignores tyres (for whatever reason, ignorance or negligence) are they really serving the interests of our communities and societies or are they just -- I should stop there but you know where I’m going!
The technology to monitor tyre pressures in real time is and has now been available for decades. The TREAD Act (USA) mandated tyre pressure monitoring (TPMS) for light vehicles in the USA in the year 2000. This year TPMS gets a key for its birthday, yes well and truly a mature product (some may say adult) and industry yet, our regulators and legislators continue to ignore the humble tyre.
The upsides of maintaining tyres at an appropriate pressure I’ve discussed previously, all positive. The same detail has been published in many papers (such as the TNO paper!) but we as an industry continue to live in the past whilst adopting hi-tech solutions for other aspects of our industries, e.g., GPS tracking, fatigue monitoring, reefer monitoring and control, real time video surveillance of the drivers and the surrounding traffic conditions. Why? To me there is little respect paid to the critical role the tyre provides for us. So many users do not consider how the tyre works for them and why the simplest of tasks will enhance the performance, yes, I speak of inflation maintenance. Without respect the tyre will never be recognised for the contribution it has made and continues to make.
I publicly and openly challenge our tyre manufacturers as a collective to mount an education campaign to enhance the level of respect the general public has about tyres. The TIA (US) and USTMA have local campaigns on behalf of their members but I consider that until the tyre manufacturers as a collective industry actual improve the level of respect for the humble tyre we will be chasing our tails on a race to the bottom. Our tyres deserve better!
What about Michelin, Bridgestone, Goodyear, Continental, BKT, Dunlop, ZC Rubber, Hankook, Pirelli, Toyo, Sumitomo, Yokohama, Kumho, MRF, Apollo, Nokian, JKTyres, Cooper, Titan, Linglong, Triangle et al?

Continental Posts Stronger Q2 Profit As Tyre Business Enters Final Phase Of Strategic Overhaul
- By Sharad Matade
- August 04, 2026
Continental reported a sharp rise in second-quarter operating profit as improved tyre profitability and cost discipline offset a subdued global market, while the German group moved closer to completing its transformation into a pure-play tyre manufacturer.
The company posted consolidated sales of EURO 4.4 billion for the three months to 30 June, down 9.1 percent from a year earlier, largely reflecting the sale of its Original Equipment Solutions (OESL) business in February. On an organic basis, sales slipped 0.3 percent.
Adjusted earnings before interest and tax (EBIT) rose 35.1 percent to EURO 570 million, lifting the adjusted EBIT margin to 12.9 percent from 9.6 percent a year earlier. Adjusted free cash flow improved to EURO 216 million from negative EURO 46 million in the corresponding period of 2025. Net income, however, fell 45.9 percent to EURO 274 million, mainly because of the spin-off of Aumovio.
In early July, Continental signed an agreement to sell its ContiTech division to Lone Star Funds, marking what it described as the final stage of its strategic realignment. As a result, ContiTech will now be treated as a discontinued operation and excluded from the group's consolidated outlook.
"We continued our positive momentum. In the Tires group sector, we achieved a good earnings margin in the second quarter, exceeding our outlook for 2026. This puts us on track to meet our expectations for the year. In early July, we also signed an agreement to sell ContiTech. Now, we are in the final phase of our realignment as a pure-play tyre manufacturer," said Chief Executive Christian Kötz.
Chief Financial Officer Roland Welzbacher said improved profitability was driven by a greater share of tyres measuring 18 inches and above, lower impacts from exchange rates and tariffs, favourable raw material prices and strict cost discipline. He added that the company expected raw material costs to rise significantly during the second half of the year and had already taken measures to address the increase.
"We significantly increased our profitability and free cash flow. The main drivers for tyres were a higher share of tires measuring 18 inches and above, lower impacts from exchange rates and tariffs, and positive effects from raw-material prices. For the second half of the year, however, we expect raw-material costs to increase substantially and have already taken steps to address this," Welzbacher said.
Continental said market conditions remained challenging during the quarter. The European replacement tyre market for passenger cars and light commercial vehicles grew by 3 percent, supported by imports, while the North American market declined by 1 percent. Global vehicle production also fell by about 1 percent year on year.
The tyres division generated sales of EURO 3.3 billion, broadly unchanged from a year earlier, with organic sales rising 0.3 percent. Its adjusted EBIT margin increased to 15.3 percent from 12.1 percent, supported by a stronger mix of premium tyres, favourable raw material prices and lower impacts from exchange rates and tariffs.
During the quarter, Continental announced several investments aimed at strengthening its tyre operations. These included a company-owned wind farm at its Korbach plant in Germany, a new automated warehouse in Mount Vernon, Illinois, and expanded tyre production capacity at its Rayong plant in Thailand.
Looking ahead, Continental expects continuing operations to generate sales of EURO 13.2 billion to EURO 14.2 billion in 2026, with an adjusted EBIT margin of 12.0 to 13.5 percent.

- By TT News
- August 04, 2026
Goodyear is set to debut its first retail concept store in Detroit, the Goodyear Motor City Garage, just in time for the 2026 Woodward Dream Cruise. The opening coincides with a historic aerial display, as two Goodyear Blimps will fly over the Motor City for the first time in nearly two decades. This dual-blimp appearance will provide a bird's-eye view of the automotive spectacle, which annually draws over 40,000 classic vehicles and more than one and a half million enthusiasts.
The new garage will open on 15th August at eight in the morning at 3075 East Grand Boulevard. This specialised auto service centre functions as a hub for car culture, similar to destination retail concepts like a Starbucks Reserve Roastery. While offering expert services such as tyre sales, oil changes, alignments, brake service and battery replacement, the space also showcases the company’s technological innovations and storied heritage.

A custom Detroit-themed Eagle racing tyre, laser-carved with a tribute to the city, will be on display alongside a 1973 Ford Mustang convertible from ‘The Mary Tyler Moore Show’ and a 1977 Pontiac Firebird Trans Am ‘Bandit’. The Dream Cruise weekend will also feature new remote-controlled mini blimps, with further details to be announced on social media. The event honours Detroit engineers who once raced along Woodward Avenue, and Goodyear’s ties to the city date back to the early 1900s when Henry Ford collaborated with the company.

The Motor City Garage exemplifies Goodyear’s broader transformation, which includes approximately 1,500 new products planned for 2026 and a focus on higher-performance tyres. As the only major tyre manufacturer headquartered in United States, based in Akron, Ohio, Goodyear is striving to become more consumer-focused and digitally connected. The company also offers mobile installation service in 28 markets, including Detroit, allowing for tyre servicing at customer locations. Woodward Avenue remains a symbolic stretch where millions of Goodyear tyres have left their mark.
Mark Stewart, CEO, Goodyear, said, "Some of the best vehicles in the world have been laying down Goodyear rubber in Detroit since Henry Ford put them on his 999 race car in 1901. From track to tarmac to trail, Goodyear makes tyres worth bragging about, and we'll be doing just that during the Woodward Dream Cruise. Whether you're an enthusiast looking for ultra-high performance or just need help picking the best tyres to get your SUV through the school pick-up line, we're looking to show you how easy Goodyear can make vehicle care. Detroit's car culture makes it the perfect place to showcase our new retail concept alongside our Mobile Garage service that can install tyres and service your vehicle right in your driveway."

Bridgestone India, a subsidiary of Japan’s Bridgestone Corporation, has marked three decades of operations in the country with a commemorative ceremony in New Delhi. The event functioned as a strategic review of the company’s deep-rooted presence in the region, bringing together a wide array of automotive executives, government officials and supply-chain collaborators. Senior management used the occasion to reaffirm the organisation's long-term commitment to the subcontinent, highlighting the mutual growth achieved through sustained industrial cooperation.
The ceremony was elevated by the presence of the Japanese Ambassador to India, H.E. ONO Keiichi, who acted as the guest of honour for the evening. His attendance underscored the diplomatic and economic importance of the bilateral ties that have supported the company’s expansion. During the proceedings, Bridgestone formally acknowledged the critical role played by its local allies and manufacturing partners, whose operational support has been fundamental to navigating the competitive Indian automotive landscape over the decades.
While the celebrations looked towards the future, they also provided a moment to evaluate the company’s evolutionary path within the country. The initial foray into India began with commercial activities in 1996, but the true industrial footprint was established two years later when production commenced at the Pithampur complex in Madhya Pradesh. Subsequent capacity enhancements, notably the 2013 addition of the Chakan facility near Pune, allowed the firm to scale its operations to meet the surging domestic demand for diversified tyre products.

In a bid to stay ahead of technological curves, Bridgestone inaugurated a specialised Satellite Technology Centre at its Pune site in 2025.

This strategic move is intended to embed advanced research capabilities directly within the local manufacturing ecosystem, ensuring that regional offerings align with global ‘Dan-Totsu’ quality standards.
As the company transitions into its next operational decade, leadership is pivoting towards a robust agenda centred on sustainable transportation and digital mobility solutions. The firm currently supplies a comprehensive portfolio covering passenger vehicles, heavy-load trucks and off-road machinery, all engineered for local climatic and road conditions. With a strengthened technological base and a mature distribution network, Bridgestone India is positioning itself to be a primary catalyst in the country’s ongoing infrastructure modernisation and vehicular safety evolution.
H.E. ONO Keiichi, Ambassador Extraordinary and Plenipotentiary to India & the Kingdom of Bhutan, said, “Bridgestone India's 30-year journey is not merely the story of the growth of a company; it is also a symbol of the success of Japan-India economic cooperation. Since its establishment in 1996, the company has grown alongside the Indian market and has made significant contributions to India's industrial development and the evolution of mobility through its investments in plants in Madhya Pradesh and Maharashtra.”
Ankit Asthana, IAS, Additional Managing Director, Madhya Pradesh Industrial Development Corporation, said, “The story of Bridgestone in Madhya Pradesh is not merely the success of one company; it is an example of how visionary corporate leadership and responsive governance can together create lasting economic and social value. This collaboration has not only contributed to the company’s growth but has also strengthened the industrial ecosystem of our state by generating employment, supporting ancillary industries and promoting responsible manufacturing.”
Nobuyuki Tamura, Member of the Board, Representative Executive Officer, EAST CEO, Bridgestone Corporation, said, “The first 30 years established a strong foundation, and the next 30 years will create new possibilities. Throughout our journey in India, we have remained guided by our Mission, ‘Serving Society with Superior Quality’, and our commitment to creating value for society through safety, sustainability, innovation and quality. India today plays a significant role in Bridgestone’s regional and global growth strategy. Looking ahead, we will further strengthen our commitment to India, including through the previously announced passenger car tyre expansion plan, preparations for which are already underway, while continuing to enhance our R&D capabilities to meet the increasingly sophisticated needs of the Indian market. Together with our partners and stakeholders, we will continue to innovate, grow and contribute to a safer, more sustainable and more connected future of mobility.”
Rajarshi Moitra, Managing Director, Bridgestone India, said, “Bridgestone India has contributed to India's growth through investment, employment generation, manufacturing excellence, technology development, local sourcing and skill development. As we enter the next phase, our focus will remain on translating Bridgestone's global capabilities into locally relevant products and solutions, strengthening responsible manufacturing, deepening partnerships across the automotive value chain, and addressing the evolving needs of mobility, society and the environment.”
Yokohama Rubber Confirms Major Tyre Supply Role For Upcoming AXCR In Thailand
- By TT News
- August 04, 2026
The Yokohama Rubber Co., Ltd., has confirmed its role as the official tyre supplier for a significant portion of the upcoming Asia Cross Country Rally (AXCR), with 12 competing teams and 20 vehicles set to utilise its GEOLANDAR M/T G003 mud-terrain tyres. The 2026 edition of Asia’s largest cross-country rally is scheduled to take place from 10 to 15 August 2026. This announcement follows a dominant streak for the tyre manufacturer, as vehicles equipped with GEOLANDAR tyres have secured the overall championship in three of the last four rallies, with victories in 2022, 2023 and 2025.
Among the prominent contenders receiving support is the defending champion, Team Mitsubishi Ralliart, which triumphed in 2025 and also claimed the title in 2022. The team is entering three Mitsubishi Triton pickup trucks for this year’s race, with a driver lineup that includes Chayapon Yotha, a two-time overall champion, Katsuhiko Taguchi and Kazuto Koide. The squad is aiming for consecutive victories on the Yokohama tyres.
Additional leading teams will also compete on the GEOLANDAR tyres, including TOYOTA GAZOO RACING INDONESIA, which previously achieved a championship and second-place finish in 2023 with its Toyota Fortuner. The roster of supported teams further includes the GEOLANDAR FORTUNER takuma-gp, driven by 2023 champion Takuma Aoki, the ISUZU SUPHAN TRANE TITANIUM YOKOHAMA NEXZTER RALLY TEAM, which is expanding to three vehicles after a fourth-place finish last year, and CUSCO Racing with two entries. Yokohama Rubber is also extending its support to diverse teams, including those featuring female drivers.

The GEOLANDAR M/T G003 tyre is distinguished by its robust and aggressive design, providing superior traction and durability across challenging off-road surfaces such as mud, gravel and sand. The tyre’s extended lifespan and reliable performance on varied terrain have been consistently validated in numerous international off-road competitions, reinforcing the brand’s reputation in the rally community.
The AXCR, first held in 1996 and officially sanctioned by the FIA, is a gruelling event comparable to the Dakar Rally. For 2026, the rally will be entirely hosted within Thailand, covering an approximate 2,000-kilometre route from Pattaya to Phitsanulok. Competitors will navigate a demanding assortment of landscapes, including mountainous regions, dense jungles, coastal beaches and agricultural plantations, testing both vehicle and tyre durability to the limit.
