TeraFlex Nomad Off-Road Deluxe Satin Titanium Wheels TeraFlex Nomad Off-Road deluxe satin titanium wheels feature a reinterpretation of the classic 6-hole design. The one-piece cast aluminum alloy rims are engineered with a "form follows function" philosophy， resulting in a technical look. With their modular plug system， the Nomads are the only wheels compatible with TeraFlex's all-new proprietary Air Deflator Valve―which allows you to quickly air down your tires to a preset pressure to as low as 10 psi. (Nomad wheels are also available in other finishes.) Additional notes: * Cast from heat-treated A356-T6 aluminum* Strong enough to handle 40 in. tires* Locking bead seat knurling allows for safely running lower air pressure * Lack of "water toughs" prevents water pooling * Dual-stage clear powdercoat with UV inhibitors* Easy-to-clean finish* Modular plug system accepts Schrader valve， wheel plug， or air deflator* Symmetrical valve holes for balance * Fully encapsulated Schrader vales to keep out contaminantsAir Deflator Valve details: * Adjustment screw sets spring preload* Releases up to 40 times more air than Schrader valve for quick air-down* O-ring seal ensures air blows contaminates away from air release orifices* Viton? O-ring can be changed without disassembly* O-ring seals pressures up to 3，500 psi* Black and red anodized finish* Not recommended for use with balance beads of fix-a-flat tire sealants
