Good Year put its G394 SST wide base trailer tire with DuraSeal to the test at Mid America Trucking show and recently revealed its results. DuraSeal consists of a yellow, gel-like rubber compound that’s released when needed to instantly seal a puncture of up to a quarter-inch in diameter in the tread area of the tire.
The company declared that its tire resisted to 367 nail punctures without losing pressure. The tire was “damaged” by different visitors which used a special device to pierce the surface with a nail.
Tim Miller, marketing communications manager, Goodyear Commercial Tire Systems said “The results were eye-popping. DuraSeal Technology is the industry’s first and only built-in tire sealant, and is designed for multiple punctures while maintaining tire pressure. If the nail is pulled out, DuraSeal can instantly fill the hole and keep air from escaping. People are amazed that a truck tire can seal itself.”
At Mid America Trucking Show, Bridgestone has launched a total tire solution which can save up to 5% on fuel costs and shave up to 29% in total tire wear costs.
Bridgestone presented five new tires in the EcopiaTM line for steer, drive, and trailer positions, and four new tread designs in the Bandag FuelTech line that complement the drive and trailer Ecopia line up.
Both product lines were developed to be used together using specially engineered compounds paired with matching retread patterns which continue low rolling resistance from the new Ecopia tires to the FuelTech retreads while extending casing life.
At Mid America Trucking Show, LOUISVILLE, Continental Tire presented a new tire pressure monitoring system developed especially for commercial vehicles.
The new system is named the ContiPressureCheck and constantly monitors the pressure and temperature of each tire on the vehicle in order to provide real-time, on-demand tire status information and to warn the driver of tire-related problems before they become a critical concern.
Clif Armstrong, director of commercial vehicle tire marketing for the Americas, said: “ContiPressureCheck is a unique product that brings together all Continental’s expertise in tires, inflation, in-cab displays, sensors and monitoring technologies for a direct system that not only provides advanced, accurate pressure data, but also addresses fleet concerns about fuel economy and operating cost reductions.”
ContiPressureCheck integrates its sensors, communication system and data processor into a single module that is housed inside a rubber container and glued to the inner surface of the tire. The sensors continuously monitor both air pressure and the tire’s temperature, and transfer data wirelessly to the truck’s electronic control unit (ECU). This processes the data, saves warnings and sends them directly to a display in the driver’s cab.
Armstrong explained: “Since a tire’s contained air pressure naturally increases as a vehicle moves, it can be difficult to tell if a hot tire is underinflated. Without some form of temperature compensation, a hot tire that is underinflated might appear to be fine, because the contained air pressure is at or above its cold inflation pressure”.
Thanks to proper tire inflation, the fleet owners will benefit from low fuel consumption and a longer life for tires which translates directly in reduced operating costs. ContiPressureCheck will be available to the North American trucking marketplace in fall 2012.
Agility Fuel Systems showcased a new line rail mounted compressed natural gas fuel systems at Mid America Trucking Show in Louisville. The new system was developed to fit seamlessly with today trucks and is available with a special outer cover made from composite material which offers additional protection it in case of an accident. The fuel tanks are attached to the rail with specially engineered break-away brackets, while an embedded wire in the composite material alerts the driver if damage is detected. Moreover, the company has also used composite materials for the straps for enhanced protection.
Barry Engle, Agility Fuel Systems CEO said :“Our new CNG systems are developed to the very specific needs of class 7 and 8 trucks, making natural gas more usable in the largest segment of the truck industry. We are really excited about the growth potential that these products will represent for Agility and to the wider adoption of natural gas in the truck industry.”
The tanks capacity ranges from 29-63 gallons of fuel and for the moment, the system is available only for Class 7 and Class 8 heavy duty trucks.
SAF-Holland revealed the new self steering integrated suspension system with lightweight Fusion Beam Technology at the 2012 Mid-America Trucking Show. The new system is fitted with disc brakes and offers a wheel cut between 20-30 degrees. The company also said that in the near future the company will also offer drum brakes configurations for a higher versatility.
The SAF CBX Self-Steer axle suspension system is designed to turn easier, greatly reducing tire wear, while improving fuel economy by reducing drag and tire scrubbing – which can also lead to frame damage, torsional stress and wear.
Thanks to the use of the new lightweight technology, the neam weight is reduced without compromising beam strength or integrity.
Various capacities are available in the series which include the SAF Self-Steer CBX23, SAF Self-Steer CBX25 and SAF Self-Steer CBX25/30. While the CBX23 and CBX25 models deliver capacities of 23,000 lbs and 25,000 lbs, respectively, the CBX25/30 offers an additional 30,000 lbs of load carrying capacity at creep speed (5 mph or less) and 25,000 lbs of capacity for on highway operation. The SAF Self-Steer CBX25/30 delivers its additional load capacity through the addition of a larger air spring.
