Michelin’s X Multi Energy D2 Regional Drive Tire Overview
Target Audience and Tire Specifications
Michelin’s X Multi Energy D2 is designed for fleets using the X Multi Energy D tire. The available sizes include:
- 295/75R22.5 LRG
- 11R22.5 LRG
- 11R22.5 LRH
Performance claims are based on the 11R22.5 LRG size, prompting fleets with the other sizes to consult Michelin for tailored data.
Performance Highlights
- 9% Lower Rolling Resistance: Achieved versus the previous X Multi Energy D (ISO 28580 testing).
- 18% Better Rolling Resistance: Compared to Bridgestone M760 Ecopia and Goodyear Fuel Max RTD (internal testing).
- 10% Improved Wet Handling: Both tires tested worn to 10/32 inch.
- 16% Better Snow Traction: Again, with worn tires.
Importance of Size and Footnotes
Fleets should focus on Michelin’s footnotes as they clarify tests were specific to 11R22.5 LRG tires. This means:
- Different sizes (like 295/75R22.5 or 11R22.5 LRH) need further validation of performance claims.
- Fleets should consult Michelin before making any quick changes.
Traction Testing Insights
The claims for traction improvements were measured on tires that were worn down to 10/32 inch. This reflects real-world tire performance under typical conditions, especially relevant for fleets in diverse weather conditions.
Durability and Retreading
The D2 features Michelin’s Duracore casing, designed for durability and multiple retreads:
- Rated for four retreads, distinguishing the performance of the original tread from that of retreaded tires.
- Retreading can extend overall tire life but might alter performance characteristics.
OEM Considerations
Michelin positions the D2 to meet environmental standards for truck manufacturers, indicating its suitability for both factory fit and replacement orders.
Conclusion
The D2’s performance and durability enhancements make it essential for fleets operating in various conditions, especially those prioritizing longer tire life and better fuel efficiency. Before switching, it is critical for fleets to understand how the tire’s performance metrics translate to their specific tire sizes.
