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?

Remember success does not reward a lack of action. (TT)

Bridgestone India has launched Project PRAVAAH, a new environmental initiative aimed at addressing severe water scarcity and ecological decline in the Dhar district of Madhya Pradesh. The programme, executed in partnership with the Society for Agriculture and Environmental Sustainability, targets the restoration of three traditional water bodies situated within a catchment zone of approximately 140 acres.

The region has historically suffered from critical groundwater depletion, with extraction rates reaching or exceeding the annual recharge capacity. This unsustainable usage has caused water tables to plummet to depths of 10 to 20 metres below ground level, particularly during the dry pre-monsoon period, severely impacting both domestic drinking water supplies and agricultural irrigation.

Moving beyond simple water conservation, Project PRAVAAH employs nature-based solutions and active community engagement to revive local ecosystems. The effort creates new livelihood opportunities for marginalised women and complements Bridgestone’s broader environmental portfolio, which already includes 9.5 acres of biodiversity parks and community gardens designed to promote conservation awareness.

The restoration project is projected to recharge up to 150,000 metric tonnes of groundwater, ensuring more reliable water access for nearby households, livestock and farms. By revitalising ponds as living ecosystems, the initiative aims to foster biodiversity, bolster community resilience against climate variability and reaffirm the company’s dedication to long-term societal and environmental well-being.

Sudhir Kulkarni, Executive Director – HR, Admin & CSR, said, “Care for the environment and the communities that it serves are core to Bridgestone’s philosophy. Project PRAVAAH aims at tackling the acute water shortage faced by communities in Dhar. With Project PRAVAAH, we are turning these ponds back into living ecosystems that will benefit these communities.”

Pyrum Innovations AG has officially entered into a binding plant purchase agreement with its Czech-based joint venture, SUAS reTire s.r.o., marking a watershed moment for the German technology firm. The agreement, covering a thermolysis system for the planned Sokolov recycling hub, constitutes Pyrum’s inaugural external equipment sale, a transaction that significantly propels its commercial footprint beyond domestic operations.

Financial groundwork for the Czech project has been firmly secured, as the joint venture concurrently closed loan arrangements with a local banking institution. This development rendered the venture fully capitalised, prompting SUAS reTire to place an irrevocable order for Pyrum’s core technology, which encompasses three reactor units and auxiliary process systems. As the primary technology partner, Pyrum will assume responsibility for harmonising all ancillary site equipment with the master control architecture.

The corporate structure underpinning the initiative sees Pyrum owning 49 percent of SUAS reTire, while the remaining 51 percent is held by SUAS Ecology s.r.o., a partnership forged in the preceding year. The JV is exclusively mandated to oversee the design, construction and subsequent operation of the advanced tyre recycling facility in the western Czech city.

Ground preparation at the industrial zone has already commenced, and the impending down payments will unlock procurement of long-lead components to uphold the project timeline. Once operational, the three-reactor train is designed to process upwards of 22,000 tonnes of scrap tyres per annum. The location’s inherent logistical edge derives from the adjacent SUAS power plant, which will permit direct conversion of pyrolytic off-gas into electricity, circumventing heavy auxiliary capital outlays. The plant is slated to begin production by the spring of 2028.

Pascal Klein, CEO, Pyrum Innovations AG, said, “By signing our first external plant purchase agreement, we have reached a significant milestone in Pyrum’s development. This achievement is the result of a long and intensive journey during which, together with our partners, we established key technical, financial and organisational foundations. We are therefore all the more pleased to have now signed our first plant purchase agreement for an external facility, which we will build together with our partner SUAS. The secured financing underlines our partners’ confidence in our technology and provides an excellent foundation for the successful implementation of the project in the Czech Republic.”
