Specialised high-precision manufacturing company Glebus Alloys has been a preferred partner of leading tyre companies across the globe for over two decades. 

Its mission was clearly defined by its founder Michael Stefanidis: “Our aim is to make manufacturing a safer place for the worker and more profitable for the shareholders by sustaining a greener and cleaner industrial environment.”

Glebus has three product lines: G-METAL, GSV and DOT Plugs.

G-METAL

Located in Poland, the company’s plant produces maintenance free, self-lubricated bearings, sliding plates and bushings under the trade name/mark of G-METAL and CERAMET.

It is a specialised material that combines unique properties for the curing department. Companies like Goodyear, Bridgestone, Michelin, Pirelli, Continental, Cooper, Hankook, Yokohama, MRF, JK Tyre and others have been benefitting from Glebus Alloys’ sliding plates for long time.

The company employs over 140 people with over four decades of combined experience in tyre curing and mould handling. Glebus Alloys takes prides in its fast, dependable and customised JIT services. It has developed products in different areas for the container shoe, top and bottom plates, axial movements and higher loads segments. 

An added value is the 5-year warranty that Glebus Alloys provides. The factory has two production sites – one for continuous sintering and one for customer sintering process – that enable it to offer high quality materials at affordable prices along with fast delivery customised to client drawings and specifications.

One of the key factors for a perfectly cured tyre is the proper closing of the mould in the container and press. Any misalignment among the three moving elements will harm the outcome of the curing process.

These misalignments, in most cases, come from the wear out of the sliding plates and guiding elements. Specially developed wear indicators can be placed on the wear plates to maintain the proper replacement period. Based on the extensive period spent in the tyre industry, Glebus Alloys has developed a self-lubricating sliding material suited especially for tyre containers. 

Glebus Alloys does not spray its wear plates with specialised coatings to make them look like sliding material. Glebus Alloys sinters and bonds its unique formulas to have a unified unbreakable material.

G-METAL self-lubricating sliding plates are especially designed to cope with unevenly distributed load and thus provide prolonged production time. Used in tandem with the wear indicators, it allows to stay on top of the issues caused by blocked container due to worn out sliding plates.

Furthermore, long raw material bi-metal wear plates of size 2,000x200 mm with a total thickness 3 or 5mm for individual custom projects are now available for order. 

GSV

Glebus Alloys is the ‘only’ worldwide patent holder for the tyre mould venting systems under the brand name GSV (Glebus Spring Vents). 

The unique demountable, three-piece design of the GSV provides a lot of flexibility that older spring vents (the one-piece type) are not able to match in anyway. 

Glebus Alloys starts by evaluating the current situation and status of the tyre curing environment and finds solutions on how companies can develop a manufacturing place for tyres with free spew, greener and less expensive. Glebus Spring Vents may replace existing vents (microvents-minivents) in the same hole and eliminate the need for expensive vacuum containers or press piping or injection type segmented moulds.

This product line employs 70 people with over 100 years of combined experience in rubber compounding, mould designing, mould manufacturing, mould cleaning and tyre curing.

The new development includes specialised stems that are focused on the surface of the aluminium mould and the machined top that is imprinted on the tyre surface. The focus on the visual aspect of the tyres has become very demanding nowadays, resulting in different stem head textures.

This development has been going on for some time now and results show that this can be amended by proper adjustment of surface parameters like different coatings, artificial increase of surface roughness to break the light reflection and special machining. 

New addition to the GSV portfolio are the specialised stems that offer customised approach to deaeration of sidewall plates during curing process due to different flow of rubber. 

DOT Plugs

RGP, a subsidiary of Glebus Alloys, is a specialised plastics production company based in Czech Republic. It is focused on specific industries and high-end precision thermoplastic projects. This is the company’s third line of product – nano-plastic DOT plugs for tyre moulds that replace aluminium or steel one. This company employs 40 people with knowledge of AI and 4.0 automation.

These punishing conditions demanded precise car control, reliable tyre traction and steadfast braking performance, making the choice of the Winter i*Pike SR10W critical for success.

Following a fierce contest, Toyota GAZOO Racing’s Elfyn Evans and co-driver Scott Martin claimed victory by a margin of 14.3 seconds, securing their second consecutive win in Sweden. Having also finished second in the season opener at Rallye Monte-Carlo, this result propelled the pairing to the top of the championship standings with 60 points.

The WRC now turns its attention to the formidable Safari Rally Kenya, scheduled for 12 to 15 March 2026 near Naivasha. This event is renowned as one of the most gruelling on the circuit, where crews must navigate extreme heat, mud from heavy rainfall and rapidly changing weather.

Hankook’s commitment to the sport extends beyond event supply. The company continues to refine its high-performance rally technology through intensive collaboration with the FIA and major automotive manufacturers, having completed over 2,000 kilometres of real-vehicle testing across eight countries. With its exclusive tyre supply agreement for all WRC classes covering the 2025 to 2027 seasons, Hankook is reinforcing its premium brand identity and solidifying its leadership in motorsport engineering.

Continental is set to make a significant impact at the upcoming Tire Technology Expo in Hannover with a strong presence at the technical conference scheduled for 3 March 2026. The company will kick off the event with a major presentation centred on the evolution of tyre technologies designed to meet the demands of autonomous driving. Dr Andreas Topp, who leads Platform Development and Industrialisation for passenger car tyres at Continental, will illustrate how the vision of autonomous vehicles is transitioning into everyday reality and how the tyre manufacturer is proactively developing innovative solutions to support this shift.

In addition to the opening session, Continental experts will deliver three further presentations, each addressing critical areas of tyre science and environmental regulation. One of these will explore the use of recovered carbon black derived from end-of-life tyres as a filler material. Professor Jorge Lacayo-Pineda, a specialist in materials evaluation, will delve into the complexities of identifying this material within vulcanised rubber compounds. Recovered carbon black, primarily obtained through pyrolysis, represents a milestone as the first industrially scalable filler sourced from discarded tyres. It is not considered a direct substitute for conventional carbon black but rather a distinct category of filler due to its unique composition, which includes carbon residues and a specific thermal background. Professor Lacayo-Pineda will examine the technological and regulatory possibilities that arise from detecting this material in new tyre compounds, focusing on reliable identification techniques such as electron microscopy and molecular spectroscopy.

Another key presentation will broaden the conversation around tyre emissions. Dr Frank Schmerwitz, a senior test engineer specialising in tyre wear, will address the limitations of current discussions that predominantly focus on tyre and road wear particles. He will highlight additional pathways of mass loss that are not captured by conventional measurements. His talk will consider the release of nanoparticles, the persistence of wear residue on road surfaces and the chemical degradation of this material due to environmental factors like oxygen and ultraviolet light, aiming for a more complete scientific picture.

The final presentation will tackle the complexities of modern tyre development in the context of new regulatory frameworks. Dr Pavel Ignatyev, an expert in rubber friction and wear physics, will discuss how the introduction of standardised abrasion limits and measurement methods under the Euro 7 regulation is reshaping innovation in the industry. He will explain the various parameters influencing tyre wear and how they interact with these new requirements. Through simplified models, he intends to demonstrate the intricate nature of tyre wear and outline the collective challenges that remain for the industry, emphasising that a deep understanding of these dynamics is crucial for translating regulatory mandates into effective technological advancements.

Dr Topp said, “The future of self-driving vehicles has begun. We are developing tyre technologies and products that meet the unique technical requirements of these vehicles. This includes topics such as interaction with smart vehicle dynamic controls, optimised fleet operations and tailored solutions for specific use profiles.”

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.”
