GCAPS physical testing expertise has led to research and new modelling methods for improved products delivered to our customers, including global vehicle manufacturers, tyre manufacturers, and championship motorsports teams. These clients have used GCAPS modelling and testing services to elevate their performance in vehicle handling, autonomous vehicle technology, and many other aspects of transportation simulation. The ability to provide these services begins with the LTRe (Figure 1).

The LTRe was purpose-built with motorsports in mind. Infused with highly dynamic positioning rates, a maximum speed range of 320 kph, high force capabilities, and electric drives enabling driving and braking conditions throughout the entire speed range makes the LTRe the most dynamically capable machine globally. High spindle torque capabilities and overall size allow GCAPS to test heavier tyres such as light trucks and some commercial truck/bus tyres.

Until the establishment of GCAPS in 2012, the motorsports industry had been limited to either on-track or low-speed machine tests to quantify tyre response. On-track test methods are adequate for simulation validation but are often not comprehensive enough to measure pure tyre response due to vehicle dynamics interference and inconsistent terrains. Low-speed indoor methods will capture tyre responses, but speed limitations result in data extrapolation in trend analysis and tyre models at higher speed ranges. Increasing speed will affect the growth of the tyre, typically shown in loaded radius measurements, thereby changing the tyre’s contact patch dimensions and directly affecting the tyres force generation. This demonstrates the importance of measuring the tyre’s response throughout the vehicle’s operating domain. A tenth of a second in motorsports can mean finishing multiple positions behind the leader. Capturing accurate data at operating speed allows teams to optimize their performance and improve lap time. The LTRe provides such measurements to reduce speed sensitivity compensations in tyre models and measure the tyre’s response more accurately with a flat contact patch interface.

Another illustration of the LTRe’s dynamic capabilities is completing drive file replays (Figure 2). On-track or simulation data can be used as machine inputs to replicate vehicle manoeuvres. This test method can be used to validate tyre models, inform construction and vehicle setup analysis, or test the tyre’s durability. The LTRe is also instrumented with premium thermal measurement sensors (Figure 3) to capture the tyre’s outer and inner carcass temperatures to monitor the thermal state of the tire, develop thermal models, and improve lap-time predictions in simulation. GCAPS has developed a thermal logic algorithm, using customer-defined locations and temperature setpoints, controlling the tyre’s position in the test sequence until the defined setpoints of the tire are satisfied. This method ensures optimal and consistent temperatures are met before testing continues with the most efficient time, which inevitably reduces thermal variations in tyre response.

Heavy emphasis has been placed on vehicle simulations to improve the performance of handling, ride comfort, and safety. These areas are desired by customers and are required to comply with federal regulations.  GCAPS Simulation group produces commercially available tyre models such MF-Tyre™, MF-Swift™, PAC2002, and FTire™. These models are widely known across the industry and used frequently in vehicle dynamics platforms.  Utilizing their dynamic, thermal, and unique cleat capabilities, GCAPS has internally developed procedure methods aimed at improving the model’s fidelity which have been verified with the tyre model creators. These capabilities ensure and improve the robustness of these tyre models by offering dynamic test data to properly characterize the tyre’s response and match innovative vehicle maneuvers.  GCAPS offers both testing and modeling at the same facility, which will improve modeling results, shorten lead times, and reduce costs.  Additionally, GCAPS simulation team has the experience and industry leading expertise to generate tyre models that improve vehicle simulations and enhance the mobility industry. 

Not all race events have ideal sunny and dry days.  Many series will continue the race as rain occurs.  To gain knowledge of the wet tyre response, GCAPS has developed a water delivery system that can apply a consistent water depth to the tyre for speeds up to 250 kph on its LTRe. Using the water delivery system, GCAPS engineers have developed procedures to not only determine a hydroplaning speed, but also how a tire performs for all conditions a vehicle may encounter on roads or racetracks. Using the LTRe coupled with the water delivery system, changes in tyre force generation are measured at various speeds, loads, cambers, pressures, and even water depth. This information provides insight into the tyre’s force generation differences, which can loop back into the stability and safety assessments in wet conditions of highway vehicles ADS technology, and motorsport vehicles.  The methodologies developed by GCAPS have been used to quantify and improve the compounds and tread pattern designs of motorsport tires. 

Motorsport tyre design requires an in-depth knowledge of tyre response, irrespective of the vehicles their placed on. Pirelli faces a new challenge ahead of the 2022 season relative to tyre design, the new vehicle aero package coupled with a change in tire size from a 13-inch to 18-inch diameter wheel. With overall tyre diameter increasing from 660mm to 720mm (~3-inch difference), a reduction in sidewall height inevitable, requiring structural changes to the tyre to maintain current performance demands and removing the team’s ability to rely on historical data increase the challenges for understanding the tyre.. Teams use historical data through race events, practices, and testing to apply setup configurations to the car. Since there is no historical data for the new tyre designs, teams will rely on testing data from both on-track and laboratory environments. It is imperative that testing be performed at a facility containing the resources and capabilities to match conditions seen on track. GCAPS provides this framework to their motorsport’s customers by removing speed compensations, helping improve vehicle setup decisions, and optimizing overall performance.

Over the years, GCAPS has developed and implemented processes, test procedures, and processing tools to improve quality assurance for their customers. These methods are used to evaluate machine health, repeatability, and data quality, which is the reason GCAPS customers can collect such comprehensive data over the span of almost a decade and trust its validity. Yearly machine calibrations are completed by GCAPS to ensure machine repeatability, giving them explicit knowledge of system components and capabilities. For their global customer’s needs, GCAPS understands the importance of time and accuracy with respect to traveling schedules and deadlines, offering adjustable operating hours and virtual attendance options to remain flexible.

In January of 2013, Goodyear Racing became GCAPS first motorsports customer, and have consistently used GCAPS capabilities to improve tyre development, becoming even more prevalent in Goodyear’s development of the new 18-inch diameter tyre being implemented in the 2022 NASCAR season (Figure 4). GCAPS continues expanding their motorsports customer base, including a variety of racing series’ from IMSA to Formula 1, and notable customers which include Pirelli Motorsports and Alpine F1. GCAPS LTRe provides an asset to the motorsports industry and is used by championship series’ across the globe. So, why shouldn’t you?

As part of a strategic effort to increase its presence in the region's premium original equipment (OE) market, Kumho Tire has confirmed its plans to establish its first tyre production facility in Europe by 2027.

The company has shortlisted Poland, Serbia and Portugal as possible locations for the plant, which is projected to need an investment of more than KRW1 trillion (USD 705 million). The decision is closely linked to Kumho’s ambition to strengthen its partnerships with European automakers and was revealed by Kumho Tire CEO during the South Korean premiere of Kumho's new Ecsta Sport tyre line.

Kumho has recently secured OE supply contracts with major brands such as Mercedes-Benz, BMW and Volkswagen Group. At the moment, Kumho runs eight tyre production plants in China, Vietnam, South Korea and the US. Its capacity to compete in the premium OE market, however, has come to be perceived as being constrained by the absence of a European production base. Through the benefits of local production, the new facility will improve response to European client requests, save freight costs and shorten delivery times, all of which will strengthen the company's partnerships.

ENSO, a London-based tyre manufacturer engaged in the production of sustainable tyres specially designed for electric vehicles (EVs), has launched its new ENSO Premium range of EV-specific ultra-high-performance (UHP) tyres aimed at drivers of high-performance EVs such as the Tesla Model 3 and Model Y.

Specifically designed for electric passenger vehicles, the ENSO Premium range comes with A/A EU-label ratings for both energy efficiency and wet grip. The tyres are designed to provide safety, increased range and a reduced total cost of ownership. Conventional tyre designs frequently fall short of the special performance needs of electric vehicles, which include greater vehicle weight, regenerative braking and higher torque loads. By lowering tyre wear and rolling resistance, ENSO Premium takes care of these issues.

The company is an authorised provider of replacement tyres for LEVC's electric taxis and has partnered with Uber to install its tyres in high-mileage metropolitan areas. The company now plans to grow throughout Europe and North America, and with ENSO Premium, it is now offering its services to individual EV owners throughout the United Kingdom. According to ENSO, the range offers advantages including longer tyre life and fewer replacements, lower energy usage, fewer charging stops and lower CO₂ emissions and tyre particle pollution.

Gunnlaugur Erlendsson, CEO and Co-Founder, ENSO, said, “We’re plugging a long-standing gap in the tyre market by offering EV drivers a purpose-built, affordable, premium EV tyre alternative that matches the innovation of their EV.”

Kraton Corporation, a leading global sustainable producer of specialty polymers and high-value bio-based products derived from pine wood pulping co-products, has announced a general price hike in North America for its SBS, SIS and HSBC product lines with effect from 1 May 2025.

Following a careful analysis of the effects of recently implemented tariffs, related cost increases and a conclusion that the company cannot independently absorb these repercussions, Kraton is adopting these pricing hikes, according to a company statement. The company further said that it will keep an eye on the scene and reassess these measures promptly in the event that conditions and US import tariffs alter.
