The Industry Grip Testing System (IGTS) is a brand new measurement trailer, developed as a joint project between tyre maker Michelin and solution provider Altracon. It comprehends the knowledge of both tyre and measurement equipment experts and represents the technical feasibility in terms of tyre characteristics measurement on the road with state of the art ease of use.

The Altracon Industrial Grip Trailer System IGTS consists of a modular concept design. One development target was to keep the system variable for existing as well as for future test- and measurement tasks and to adapt to any kind of on the road testing requirement.

The IGTS grip testing trailer is built for straight dry and wet-braking tests. The trailer’s frame and wheel load station are optimised by FEM technology for highest stiffness and lowest deformation.

Design features

The trailer is made of a stiff frame with independent wheel suspension for the left and right wheels and is equipped with a variable towing bar to level different heights of the vehicles hitches. It may be pulled from any drawing vehicle with sufficient trailing load and engine torque for the measurements, no matter if it is a Pick-up, SUV, or truck. The IGTS hosts an independent test wheel load station. It is placed in the center of the trailer between the carrying wheels and presses the test wheel to the road surface on a path between the trailer wheels. The test-wheel load station is equipped with a high-performance disk brake to apply the braking torque/ force to the test wheel for grip testing. All functions are independent from the drawing vehicle while it carries all the necessary supplies on board except of the water tank, which is carried by the drawing vehicle.

The concept design is prepared to be extended with dynamic test capability with camber and slip variation, which will be included in the IGTS “Force and Moment” trailer. The test wheel load station and its media supply and control system may also be built into other vehicles such as busses or trucks, which must be prepared accordingly as a matter of course. 

The trailer is equipped with a modular undercarriage set-up. The basic trailer requires only one axle to perform grip measurements, which are done straight rolling/ braking. The directional stability of the trailer is enhanced by two additional lift axles, one in front and one behind the carrying axle of the trailer, to run dynamic tests with the IGTS on the road when it is equipped with camber and slip variation functionality. These lift axles are only used during the actual measurement and will be lifted for taxiing and transportation. Both axles use smaller wheels than the carrying axle and also have independent wheel suspension. The wheels of the lift axles are moreover actively steered to balance side forces which may be generated during testing. The drive performance control system adjusts the trailers’ Eigen modes in vertical and lateral direction and significantly improves the directional stability.

The IGTS test wheel load station is light-weight to reduce the effect of mass of inertia. It is equipped with an active wheel load control while previous test trailers just use dead weights. A fully automatic and adjustable damping control at the testing axle adjusts the Eigen mode and cares for smooth running and best precondition for the measurement on any road. The high-performance long-life wheel spindle is specially designed for lowest rolling resistance.

Power supply is done by batteries, which are loaded by generators. These are inbuilt to the carrying axle at each side. The power supply engineering may be designed as 48V DC as well as 240/400 1- or 3-phase AC with converter for special applications.

Compressed air is supplied from an inbuilt compressor with air tank for inflation pressure adjustment or control as well as for connection of air driven tools.

Hydraulic supply from an inbuilt hydraulic pump system with accumulator tank enables dynamic load, brake, and steering function.  The high-speed characteristics of the hydraulic supply is suitable to simulate braking performance (ABS) and quick release brake pressure at the test wheel. It allows to run up to 8 repeatable tests per 100 m in a sequence in combination with the high-performance brake-control techniques.

The optional water management system is integrated and allows controlled watering of the test-wheels path. The nozzles are placed in front of the test wheel. Their watering width is adjustable to 420mm and their watering height is controlled by flow-measurement, which is adjustable between 0 and 4mm at maximum speed of 100 km/h. The system is operating with continuous water flow for quickest reaction times. It is pressure-controlled and switches between circulating and spraying mode without any time lag and pressure loss.

Measurements

The trailer speed measurement is precisely done directly at both carrying wheels. Different speeds measured at the left and right side indicate deviation from the straight path. The alignment of the drawing vehicle and the trailer is moreover precisely measured with a laser-based alignment measurement system if the IGTS is equipped with camber and slip variation functionality. Inputs from both, the speed and the alignment measurement system, will generate correction of the directional stability by the control system.

The wheel speed of the test-wheel is precisely measured directly at the test-wheel spindle with an encoder, which also gives information about the braking process of the test wheel.

Forces and moments at the test wheel are synchronously measured in x- and z-direction with 1-component sensors. A multi-component force and moment dynamometer, which may use strain gauge or quartz technology, is optionally available as an alternative. It is integrated to the wheel spindle, fully covered and shielded. However, both set-ups are available either independent or together.

All measurements of motion are done with precision sensors, using various technologies, depending on the entire parameter. For referencing, speed and location recording different control and measurements techniques are used as well.

Ergonomics

The test-wheel carrier design enables to turn the wheel by 90° around its vertical axle for wheel exchange and service. This allows the operator to access the wheel fixation from the back of the trailer.

A new milestone in agricultural tyre technology has been achieved through the partnership of Titan International, Inc. and Cerebrum Sensor Technologies, Inc. Together, they have unveiled Titan Pressure Perfect (P2), a smart sensor system designed to transform how farm tyres perform and communicate. This system marks the emergence of a broader category known as Intelligent Tyre Solutions (iTS), developed jointly by the two companies.

At the core of Pressure Perfect (P2) is real-time monitoring of tyre pressure, temperature and load. This data enables continuous oversight and works seamlessly with onboard inflation systems, allowing automatic pressure adjustments while the vehicle is in motion. Whether shifting from roadway to field or responding to varying load demands, the system can reduce air pressure by as much as half. This flexibility helps lower soil compaction by up to 35 percent and has been linked to potential corn yield increases of four to six percent.

Pressure Perfect is compatible with all Titan and Goodyear Farm Tyre products and integrates with nearly all inflation management systems already in use. By supporting more precise tyre management, it contributes to longer tyre life, improved machine efficiency and reduced environmental impact through less ground disturbance.

The innovation draws on Cerebrum’s licensed portfolio of patented technologies, including advanced sensors, proprietary algorithms and sophisticated software capabilities. This technical foundation sets a new standard for intelligent tyre management in agriculture. While other industry players focus on replicating existing central tyre inflation and tyre pressure monitoring systems, Titan and Cerebrum are advancing a more comprehensive and forward-looking approach. Pressure Perfect reflects Titan’s longstanding engineering heritage and its continued commitment to leading the field through purposeful collaboration and applied innovation.

Dubbing it the ‘Holy Grail’ of innovations, Scott Sloan, Global Ag & LSW Product Manager for Titan, said, “This is the first system of its kind that delivers dynamic inflation management. Load, tyre pressure and temperature data are gathered by a single tyre-mounted sensor and integrated with tyre-industry load-inflation tables in real time. Imagine bringing together Central Tyre Inflation System (CTIS) and Tyre Pressure Monitoring System (TPMS) technologies, and now they can work together and talk to each other – all without operator intervention."

As urban areas around the world grow increasingly louder, traffic noise has emerged as a critical environmental and public health challenge. Recognised by health authorities as a major risk factor, this pervasive issue extends from European cities to megacities across Asia and Latin America. Continental is addressing this problem by pioneering tyre technologies that significantly reduce rolling noise, thereby contributing to quieter urban environments and enhanced in-vehicle comfort.

The transition to electric mobility has brought tyre noise into sharper focus. With the near-silent operation of electric motors replacing traditional engine sounds, the acoustic contribution from tyres becomes far more prominent, even at moderate city driving speeds. In response, Continental engineers have developed specialised solutions that target noise generation without compromising the safety, durability or performance of the tyre.

One such innovation is the Silent Pattern tread design, featured on models like the EcoContact 7. This technology disrupts the conventional, uniform arrangement of tread blocks that typically creates a rhythmic humming sound on pavement. By intelligently varying the spacing and angles of these blocks, the pattern breaks up this acoustic consistency. Furthermore, it is tuned to cancel out specific sound frequencies, akin to the principle behind noise-cancelling headphones. This results in a measurable reduction of traffic noise at speeds around 50 kmph, where rolling noise is most perceptible to pedestrians and residents.

For reducing noise inside the vehicle cabin, Continental employs its ContiSilent technology. This involves lining the inside of the tyre with a lightweight polyurethane foam that absorbs vibrations caused by the tyre’s contact with the road. By dampening these air vibrations, the technology can cut perceived in-cabin rolling noise by up to nine decibels – a reduction the human ear experiences as nearly halving the volume. This substantial increase in acoustic comfort is integrated into various product lines, including high-performance summer tyres, without affecting driving dynamics or efficiency.

The company’s commitment to low-noise mobility spans multiple vehicle segments. From the Conti Urban NXT for city buses to passenger car tyres like the EcoContact 6 Q and van tyres such as the VanContact A/S Eco, these products are designed to meet stringent noise standards. Consumers can readily identify these quieter options through regulatory labels, like the EU tyre label, which provides clear decibel ratings for external rolling noise. Through these continuous advancements in tread design and sound-dampening materials, Continental is systematically working to diminish the acoustic footprint of road traffic.

According to Achillefs Tsotras, head of Continental’s Tyre-Vehicle Interaction department, “Noise, especially traffic noise from cars, buses and delivery vehicles, is a major burden for people and the environment. With tyre technologies like ContiSilent and innovative tread designs, we are actively reducing rolling noise without compromising safety. This makes every ride noticeably quieter, benefiting drivers, pedestrians, residents and the environment alike.”
