E2C® solutions can improve performance in a variety of off-the-road (OTR) tire types and can help tire manufacturers to achieve sustainability goals.
The formulation of tread compounds is one of the most important considerations in OTR tire design as it can affect the overall ability of the tire to resist abrasion, cutting and tearing; to minimize hysteresis (energy loss) and improve fuel economy; and to grip the road and handle responsively.
E2C® solutions have been shown to break critical trade-offs in OTR tire design by both lowering operating temperatures and extending the life of tires for more efficient operation. In addition, because tires made with E2C® solutions last longer and are more energy efficient, raw material consumption and CO emissions are reduced and fewer end-of-life tires are generated.
Earthmover tires must perform in a wide range of severe operating environments. These environments require tires with high abrasion resistance and the ability to resist damage from cutting, chipping or chunking from rough/uneven surfaces. In addition, large OTR tires require rubber compounds that minimize hysteresis to reduce failure due to excessive heat build-up.
Aero tires have unmatched expectations for safety and low mass. Rapid heat buildup and thermal cycling occurs more in aviation applications than anywhere else. Extending the life of tires in these environments means less downtime and lower operating costs for end customers.
Agriculture tires often must survive harsh cut and puncture requirements. Solutions that can reduce early life failures while enabling advanced tire design due to superior compound properties can play a key role in improving customer satisfaction and outcomes. In fact, recent advances in the design of agricultural tires have been proven to improve crop yields.
Port and industrial tires are responsible for moving vast amounts of goods for customers where uptime and long life are a priority. Balancing needs between tread durability and heat buildup are essential to delivering the best customer experience in these applications.
Retreads can extend OTR tire life while reducing the number of waste tires generated – a key benefit for mining operators challenged with optimizing their haulage operations for productivity while reducing costs and improving the environmental footprint of their operations.
