In July 2018, Michelin put on the "armor" for underground mine loaders and transport tires. The Michelin PRO series was released globally, and the underground mining tires XSM D2+ and XMine D2. With TA, the "treasure path" will be even more Smooth. Seemingly "soft ribs", in fact, "armor" As the most "hard bitter" tires, tires working in underground mines are easily scratched by gravel and debris, and they are also easy to smash on the tunnel walls, and the cracks and scratches on these sidewalls are likely to spread and penetrate. In the fetal body, it has an adverse effect on the safety of mine operations. Michelin's new PRO series of underground mining tires XSM D2+ and XMine D2, innovative NRF technology, adds two strong nylon "protective layers" in the sidewall to achieve greater damage resistance. In addition, the new cable design tread and upgraded belt structure double the tire's “defensiveness†and can be handled in tough environments. TA is very long-lived and safe. Downhole mining tires, which are often operated in a low-pressure environment, are prone to punctures when the air pressure inside and outside the tire is not balanced. Michelin, which emphasizes safety, requires extremely high resistance to damage to engineered tires under severe conditions. In addition to innovatively improving the carcass design of downhole mining tires XSM D2+ and XMine D2, Michelin has upgraded the rubber formulation of the tires, increasing tire load capacity by 18% compared to the previous generation, significantly increasing tire life and reducing the risk of tire puncture. .

The extremely "bad" daily working environment faced by engineering tires is critical to the tire's ability to resist damage in underground mine operations.
