Some airlines may pay for their tyres by the retreads. There is an initial payment for the virgin tyre, and then a subsequent payment for the initial retread and further payments until the tyre account is settled. If the tyre fails prior to the final payment being made, then the tyre manufacturer wears the cost.

The secret (not so secret really!) to a successful retread programme is the pressure maintenance regime. If the appropriate pressures are applied to the tyre during its initial life, then we are able to deliver a sound virgin casing/carcass to the retreading plant.

In speaking with so many retreading facilities, they all detail a high rejection rate of casings submitted for retreading. The primary reason for rejection is the breakdown of the tyre’s structure as a result of under inflation.

So how does this affect the use of resources and subsequent emissions?

I have sighted figures purported to have been produced by the global accounting firm Ernst & Young (now EY), which detail a 70 percent reduction in natural resource extraction, 19 percent reduction in water consumption (potable water is one of the next global issues to deal with) and 21 percent reduction in air pollution. A truck tyre casing (say 11R22.5) that is retreaded will reduce oil consumption by about 50 litres – obviously more for a larger tyre.

Many tyre OEMs do promote the retreadability of their casings; it is just plain economic sense when you stop to think about it. Acquiring a product where you use 30 percent (by weight) only to then throw the rest onto the scrap pile is economic stupidity, but that is what seems to happen in most road transport organisations.

Maintaining tyre inflation pressures is too difficult, they say. Well, yes, if you are stuck in the 1950s where the only way to check inflation pressure was to use a manual gauge. In the 2000s, we started using tyre pressure monitoring systems (TPMS) to gain real time information about tyres in operation. Now we can stream data and identify issues such as binding brakes, wheel ends in failure mode as well as inappropriately inflated tyres. We’ve tuned operating tyres so that tyres operate in unison or as a team across an axle and so over the entire vehicle. Not being able to view tyre pressures in real time is so last century.

By tuning the inflation pressure of a tyre, the structural integrity can be assured so that when the tread worn tyre is presented at the retreading facility, it is accepted rather than rejected.  Thus, a serious saving in resource use is generated; there is a substantial reduction in emissions as well as reduction in land use both from the initial growing of the natural rubber to the reduction of land fill.

A simple act can generate substantial savings. Why do so many educated people ignore this aspect? Why do bean counters not consider tyres in a holistic manner?

Purchasing a ’cheap’ tyre may appear to ‘save money’, but more often than not, the cost of operations actually rises. HOW? I hear the abacus jockeys cry!  A low-cost tyre more often than not has a higher rolling resistance than a quality casing. Research and development costs, low cost operators that have copied or cloned don’t bear these costs.   Consider the fuel burn over the life of a tyre, say 150,000 km. A two percent saving on the fuel burn equates to how much? When we consider the actual life of the low-cost tyre, more than likely it requires more maintenance, so there is more downtime, added rotations to gain the maximum wear from the tread package and then there is the disposal fee on the spent casing as it cannot be retreaded.

Considering tyres in a holistic manner is not something bean counters consider or actually even know about. Tyres directly influence the fuel burn of a vehicle, the wheel end life and the suspension life, even affecting the driver’s fatigue levels – not to consider the environmental aspects such as emissions and disposal.

So if an aircraft can take off and land safely on retreaded tyres, then why can’t on-road transport trucks use retreaded casings? It comes back to the neglect shown to the tyre during the initial life. It seems that people just don’t care; they don’t understand the criticality of appropriate tyre inflation pressures.

Within the Performance Based Standards for high performance trucks operating on Australian roads (think triple trailers running quad axles), there is a statement that succinctly details what a tyre contributes, to wit  ;

“All the forces needed to both support and guide a vehicle ultimately arise in the area of contact between the tyre and the roadway. These forces are generated at the road surface in response to the deformation of the tyre structure.”

As tyre deformation is the product of inflation levels, there is a direct relationship between tyre inflation levels and vehicle safety. Why do people choose to ignore tyre inflation when it is so easy to monitor and comes with so many positive benefits?

So installing a simple regime of monitoring tyres in real time tyre casings to evidence   that the tyres have not experienced a low pressure event (so destroying the casing’s integrity) means they can be selected for retreading. This eliminates the main excuse for not retreading, i.e. the rejection rate is too high. It is that simple!

A cheap tyre is not necessarily an economic positive. A well-maintained quality tyre will generate savings upon savings and then will also be able to do it all over again after retreading.

Many governments mandate the use of retreaded tyres on utility vehicles as it is well understood there is not only an economic benefit but an environmental benefit too!

If we, the global community, continue to consume resources without considering a reduction in the rate of consumption, then we’re doomed to exhaustion. Using a resource (read tyre) at only 30 percent and then disposing it of does not make any sense (nor cents!). Retreading of tyres is a sound practice based upon sound science. Why are so many businesses throwing their hard earned cash away because the abacus jockeys don’t know and don’t care about tyres?

Success does not reward a lack of effort. How much effort are your bean counters making in respect of tyres ?

The concluding day of 2026 F1 Pre-Season Testing at the Bahrain International Circuit saw Charles Leclerc set the overall fastest lap of the entire six-day programme. The Ferrari driver delivered a time of 1:31.992s on the C4 compound Pirelli tyres during the final hour of running, improving by eight-tenths of a second on the previous benchmark established by Kimi Antonelli. This performance placed him ahead of Lando Norris in the McLaren, who recorded a 1:32.871s on the C3 tyre. Max Verstappen and George Russell followed, with times of 1:33.109s and 1:33.197s, respectively, both also set on the C3 compound. Notably, none surpassed Leclerc's own leading time on that particular compound, a 1:32.655s. Pierre Gasly rounded out the top times, utilising the softest C5 tyres to post a 1:33.421s.

The C5 compound saw limited use on the final day, employed only by Alpine and Williams for short-run simulations. Aston Martin, despite having the tyre available, opted not to run it and instead completed just six laps on C3s before their session was curtailed. In contrast, teams focused on different aspects of performance. Gabriel Bortoleto and Arvin Lindblad set the pace on the harder C1 and C2 compounds, respectively. The day was also notable for the absence of several drivers, including Fernando Alonso, Lewis Hamilton and Alex Albon, who did not participate in any track action.

Beyond outright speed, teams dedicated significant effort to long-distance evaluation. Gabriel Bortoleto completed 25 laps on the C2 compound for Audi, while Esteban Ocon undertook 24 laps on C1s for Haas. Ocon was also the sole driver to run intermediate tyres, completing four laps to assess front wing behaviour. Over the entire six-day test, a total of 41,366 kilometres were covered across all 11 teams, a distance exceeding the Earth's circumference. The C3 compound proved the most popular, accounting for 61 percent of all laps. In total, 591 sets of slick tyres were utilised throughout the pre-season, with 326 of those deployed in the final three days alone.

Mario Isola, Pirelli’s Motorsport Director, said, “The radical changes introduced to the cars have inevitably shifted the teams’ focus towards power units and aerodynamics rather than tyres over the last few days. The final stages of testing are usually dedicated to optimising the car-tyre package, but it is clear some teams haven’t reached that point yet. Generally speaking, track feedback has been consistent with our simulation expectations. Drivers were able to gain confidence with the entire Pirelli range through both performance trials and long runs, even using the C4 and C5 compounds which aren’t particularly suited to a circuit like Sakhir.

“Mechanical resistance appeared strong across all options, with no signs of graining or blistering. Degradation levels are almost certainly higher now than what we expect for the Bahrain race, when temperatures will be lower and cars more developed. A central theme this season will certainly be balancing temperatures between the axles, especially ahead of the first race in Melbourne. The lower loads of a street circuit might require more intensive tyre preparation or differentiated tyre blanket temperatures, particularly in qualifying. In any case, it will be interesting to discover in Australia how much teams have been ‘sandbagging’ their engine power to avoid showing their hand. We only have to wait a couple of weeks to see the true pecking order.”

Radar Tires, a globally recognised manufacturer known for its off-road and high-performance products, is broadening its footprint in the light truck and off-road vehicle segment with a major expansion of its popular Radar Renegade-X line. Responding directly to robust market demand and the model's sustained success among enthusiasts, the company will introduce nine new sizes featuring rim diameters from 18 to 26 inches. A key highlight of this expansion is the debut of 26-inch options, catering to the growing trend of customised and lifted trucks requiring larger wheel fitments.

Since its market introduction, the Renegade-X has built a strong reputation for delivering uncompromising off-road capability without sacrificing on-road civility. Consumer feedback consistently praises its superior traction in mud and rocky terrain, its robust durability and notably low road noise – a combination rarely achieved in the mud-terrain category. This balance of aggressive performance and refined driveability has solidified its appeal.

The tyre’s distinctive design is the result of a collaboration with the renowned Italian design house GFG Style, blending engineering rigor with premium aesthetics. Its technical features include a high void-to-lug ratio designed for effective self-cleaning in mud, alongside a specialised rock-crawl compound for enhanced grip on varied surfaces. Durability is addressed through a three-ply sidewall construction, while a strategic combination of stone ejectors and serrations protects the tyre casing. Furthermore, sidewall lugs inspired by stealth design not only contribute to a striking visual profile but also improve lateral traction in challenging conditions.

The newly added sizes are intended for a wide range of vehicles, including Jeeps, pickup trucks and full-size SUVs. Availability is scheduled to commence through authorised dealers in February 2026, with additional sizes arriving through April of that year.

Rob Montasser, Vice President, Radar Tires, said, “The response to the Radar Renegade-X has exceeded our expectations, and our dealer partners have consistently requested additional sizes to meet customer demand. This nine-size expansion, including our first 26-inch rim diameter sizes, demonstrates our commitment to providing dealers with a comprehensive product offering that supports sustained, profitable growth while giving consumers more choices for their vehicles.”

Nokian Tyres has formally released its climate transition plan, a comprehensive roadmap guiding the company’s decarbonisation efforts. This strategy is anchored in the company’s near- and long-term climate objectives, which received validation from the Science Based Targets initiative in 2024. Crucially, the organisation’s ambition to achieve net-zero emissions across Scope 1, 2 and 3 aligns with the stringent requirements of limiting global warming to 1.5°C, as dictated by contemporary climate science.

The company has already made significant progress, particularly within its own operations. By the close of 2025, Nokian Tyres had successfully reduced absolute Scope 1 and 2 emissions by more than 38 percent relative to the 2022 baseline, edging closer to its interim target of a 42 percent reduction by 2030. The newly published plan elaborates on this trajectory, detailing the primary sources of emissions and the essential strategies for reduction both internally and across the broader value chain. These actions are designed to meet the 2030 benchmarks while maintaining a clear pathway towards the ultimate goal of net-zero greenhouse gas emissions by 2050.

Endorsed by the company’s Board of Directors, the plan is a living document subject to updates as emission-reduction technologies and methodologies evolve. Further details are accessible on the corporate website. This strategic approach is already yielding tangible results and external recognition. The company’s Romanian facility stands as the world’s first full-scale tyre factory to achieve zero CO2 emissions in its own operations. Furthermore, this commitment to sustainability was acknowledged in 2025 by TIME Magazine, which named Nokian Tyres one of the World’s Most Sustainable Companies, and by CDP, which awarded the firm its sixth consecutive leadership-level score for climate action.

Paolo Pompei, President and CEO, Nokian Tyres, said, “Our work towards net-zero emissions is not only about us but also about drivers worldwide. Through our actions and innovations, we reduce the environmental impact of tyre manufacturing while delivering the safety and quality that define Nokian Tyres.”
