4x4 Diamaris 255/50R 20

The luxury sport solution for the BMW X5, Porche Cayenne S and Cayenne Turbos, the 4x4 Diamaris from Michelin is also available in smaller diameters for other types of light trucks. A continuous rib design creates enhanced steering which in conjunction with large shoulder blocks improves cornering as well. The asymmetric, wet weather tread pattern optimizes hydroplane resistance by channeling water away from the contact pad creating better grip in inclement conditions. 4x4 Diamaris tires maintain their shape at high speeds due to High-Speed Confidence BAZ technology.

Features & Benefits

  • High-Speed BAZ construction
  • Enhanced steering
  • Wet weather traction features
