Hanover, 25 August 2015. Continental Commercial Specialty Tires (CST) presents two new tire solutions for off-the-road applications (OTR): the Conti EM-Master E3/L3 and E4/L4 as well as the Conti RDT-Master E4. The tires are customized for the specific demands in the construction and earthmover segment. The newly developed tread pattern designs make each solution a perfect fit for different environments, ranging from soft, muddy soil to solid terrain. Regardless of the application conditions, both products offer excellent traction and high cutting resistance.
With the introduction of the new OTR tire products, Continental CST enhances it comprehensive specialty tire portfolio and underlines its business ambitions in the construction sector. “The Conti EM-Master E3/L3 and E4/L4 and the Conti RDT-Master E4 are once more successful outcomes of our customized solutions strategy,” says Christian Luther, Product Line Manager Earthmover Tires at Continental CST. “In view of our expansion strategy 2025, we will continue to expand and optimize our product and service portfolio in the segment of construction and mining in the course of the coming years.” The first tires will be available at the end of 2015. Further sizes and tire solutions are planned for 2016 and beyond.
Whether muddy soil or rocky terrain: the Conti EM-Master is available in two versions which are each perfectly tailored for the specific demands in OTR applications. The Conti EM-Master E3/L3 is especially suited for application in muddy and soft terrain, while the Conti EM-Master E4/L4 is an excellent option for use in gravelly and rocky grounds. The reason is that both tire solutions offer different tread design features. The Conti EM-Master E3/L3 features a normal tread depth and wider spacing of blocks than the Conti EM-Master E4/L4. This results in excellent self-cleaning characteristics, powerful traction, and good maneuverability which facilitate the use in muddy terrain. The open tread design and normal tread depth (100 percent) of the E3/L3 tire version further offers better cooling and therefore less heat buildup for a long service life.
Compared to the Conti EM-Master E3/L3, the E4/L4 tire version features a greater block size with less spacing between the blocks and a deeper tread depth. Therefore, the new tire solution offers a higher carcass protection and superior cutting resistance, minimizing the risk of punctures and downtimes. The less tread block spacing also results in a smoother running even on hard surfaces. Due to a high tread wear volume, the Conti EM-Master E4/L4 offers an even longer service life compared to the E3/L3. Both Conti EM-Master E3/L3 and E4/L4 will be available in the sizes 23.5R25, 26.5R25, and 29.5R25; the Conti EM-Master E3/L3 additionally also in the size 20.5R25. The tires are therefore perfectly applicable on articulated dump trucks (ADTs), loaders, and dozers.
The Conti RDT-Master E4 is designed for the transport of extra-heavy loads. The special tread design with a deep tread depth and a wide and flat tread radius offers a high loading capacity and cutting resistance. The angled edges and the open shoulder design allow for higher lateral stability which results in better driving behavior and maximum traction even on curvy terrain. In addition, the special tread design results in excellent cleaning characteristics on muddy ground. The RDT-Master E4 will be available in the sizes 18.00R33, 21.00R33, 21.00R35 and 24.00R35 and is suitable for heavy-duty construction vehicles such as rigid dump trucks.
To increase the safety and efficiency of vehicle fleets in heavy-duty applications such as construction, quarrying, and mining, the proven ContiPressureCheck™ monitoring system can be easily mounted on both Conti EM-Master E3/L3 and E4/L4 and Conti RDT-Master E4. Due to automatic monitoring of the tire pressure, the risks of puncture accidents are reduced which offers more safety for both driver and vehicle. Correct tire pressure further leads to lower energy consumption of the vehicles and to increased mileage capability. Fleet operators can significantly reduce their operating costs and increase the efficiency of their fleets by using ContiPressureCheck™. At the same time, the environmental impact is downsized, since CO2 emissions are reduced and the life of the tire is extended.
