“We spent considerable time in the field listening to mine operators about their tire needs and used that input to help design the second-generation 007 MFT product line,” says Dana Zahuranec, tire design specialist. “The biggest issue facing mine operations is overall tire durability. The second-generation of 007 MFT tires improves durability by greatly reducing internal heat generation.”
It is designed to run in difficult environments where casing penetration and sidewall cuts are a major issue. Titan’s testing shows that the nylon casing design ran 15 percent cooler than the steel casing in an equivalent tire. “This makes the tire less susceptible to sidewall fatigue and cut damage, making the casing more retreadable,” according to Zahuranec.
A new belt package provides a more durable design. Overall tire durability was also improved with changes to the compounds, which helps reduce overall heat generation and improves the cut, chip and wear characteristics of the tire, says Zahuranec.
Sipes have been incorporated into the tire lugs, which provides additional traction and significantly improves the heat dissipation. A non-solid center tread design also helps reduce internal heat generation and allows the heat to more easily dissipate, reducing tire running temperature, Zahuranec continues.
The reduction in running temperature allows the end user to run haul trucks longer distances and at a higher speed, while still maintaining an operating temperature that is within the tire’s tolerances. A lighter construction helps reduce overall heat generation as well.“The next generation 007 MFT tires have been designed to end- users’ needs and the modifications have been verified through finite element analysis,” says Zahuranec. “We also validated the tire’s performance using our industry- exclusive radial fatigue testing machine. We put these tires to the test to help ensure their performance in the field.”
Sizes include 59/80R63, 53/80R63, 40.00R57 and 27.00R49.
