Patented "On-Board" Balancing Technology

Centramatic's time-tested system features a permanently sealed ring filled with hardened durametal alloy and proprietary synthetic fluid. As you drive, centrifugal force automatically shifts this media to counteract heavy spots.

• Smoother Ride: Virtually eliminates cab vibration and road shock, significantly reducing driver fatigue.

• Extended Tire Life: Proven to increase tire longevity by 25%–50% by preventing irregular wear and cupping.

• Lower Operating Temps: Reduces tire heat by 8%–10%, which is critical for preserving tire casings on heavy motorhomes.

• Dynamic Adjustment: Automatically compensates for mud, snow, or uneven wear patterns at speeds above 20–22 mph.

Rugged & Maintenance-Free

• Zero Upkeep: A sealed, self-contained system—just install and drive.
