15x8 IMCA Silver Beadlock Inertia 5x5

The 15x8 IMCA Silver Beadlock Inertia 5x5 wheel from Bassett is purpose-built for circle-track racing, dirt modifieds, and IMCA competition vehicles where lightweight construction and maximum sidewall support are essential. This beadlock design locks the tire bead directly to the wheel rim, preventing tire roll during aggressive cornering and hard acceleration—critical when every lap counts.

Built with Bassett's proven inertia-friendly design, the 15-inch diameter and 8-inch width provide optimal weight distribution while maintaining lateral stiffness during high-speed transitions. The silver finish offers both aesthetic appeal and corrosion resistance in demanding track environments. At 22.5 pounds per wheel, this is substantially lighter than standard street wheels, reducing unsprung mass and improving suspension response.

The integral beadlock ring system clamps the tire bead with absolute security, eliminating sidewall flex that can rob horsepower and cause unpredictable handling at the limit. This wheel is engineered for drivers and teams who demand competitive advantages on dirt and asphalt oval tracks. The 5x5 bolt pattern (five-lug, 5-inch diameter) remains common across many American domestic race platforms, though fitment verification with your specific chassis is recommended.
