Konig Flow Forming Technology
The Konig Hypergram utilizes advanced Flow Forming Technology, a manufacturing process designed to improve wheel strength characteristics while reducing unnecessary weight.
Flow forming begins with a cast aluminum wheel blank that is placed on specialized machinery. The wheel is rotated while specialized rollers apply pressure to the barrel, forming it to its final dimensions.
This process stretches and compresses the aluminum material, improving its mechanical properties while allowing efficient material distribution throughout the wheel barrel.
Flow forming provides several performance advantages:
Reduced wheel weight compared with many traditional cast wheel designs.
Improved barrel strength characteristics.
Increased tensile strength.
Enhanced material elongation properties.
Efficient material distribution.
Reduced unsprung mass when replacing heavier wheels.
Reduced rotational mass.
Lightweight construction suitable for performance-oriented applications.
Although flow forming shares certain characteristics with forging, the Hypergram is a Flow Formed wheel, not a fully forged wheel.
This manufacturing process allows Konig to offer lightweight performance-oriented wheels while maintaining a practical price point.
Lightweight 12-Spoke Design
The Hypergram features a distinctive 12-spoke design inspired by motorsport wheel construction.
Its angular spoke geometry creates an aggressive appearance while maintaining an open layout that provides visibility of the vehicle's brake components.
The spoke arrangement emphasizes the wheel's performance-oriented design and complements vehicles equipped with upgraded suspension, brakes, and tires.
Premium Matte Grey Finish
The HG8851445G features Konig's distinctive Matte Grey finish.
Unlike traditional gloss-painted wheels, the matte finish provides a subdued, non-reflective appearance that emphasizes the Hypergram's angular spoke geometry.
The gray color offers a modern alternative to conventional black, silver, or bronze wheels while complementing a wide variety of vehicle exterior colors.
The Matte Grey finish provides several styling advantages:
Clean, understated appearance.
Reduced visual reflections compared with gloss finishes.
Enhanced definition of the 12-spoke design.
Distinctive motorsport-inspired styling.
Versatile color compatibility.
Modern aftermarket appearance.
This finish is particularly appealing for enthusiasts seeking a performance-oriented wheel with subtle, refined styling.
Lightweight Flow Formed Construction
The Hypergram's Flow Formed aluminum alloy construction provides a practical balance of reduced wheel weight, strength, and durability.
Reducing wheel weight can provide performance benefits when replacing heavier factory wheels, including:
Reduced unsprung mass.
Reduced rotational mass.
Potential improvements in suspension responsiveness.
Potential improvements in steering response.
More responsive acceleration and braking characteristics compared with heavier wheel and tire combinations.
Actual performance differences depend on the weight and specifications of the original wheel and tire package.
18x8.5 +45 Wheel Fitment
The 18x8.5-inch configuration provides a versatile platform for appropriately sized street and performance tires.
The +45mm offset determines the wheel's mounting position relative to its centerline and affects both inner suspension clearance and outer fender clearance.
Compared with an otherwise identical +35mm offset wheel, the +45mm configuration positions the wheel approximately 10mm farther inward.
This may improve outer fender clearance while reducing inner suspension clearance.
Potential installation considerations include:
Factory or aftermarket suspension clearance.
Brake caliper and rotor clearance.
Tire width and sidewall selection.
Fender clearance.
Steering clearance.
Alignment and camber settings.
Hub-centric ring requirements.
Vehicle-specific tire diameter requirements.
Proper fitment should always be confirmed before installation.
73.1mm Center Bore
The Hypergram HG8851445G features a 73.1mm center bore.
Vehicles with smaller hub diameters may require appropriately sized hub-centric rings to help center the wheel during installation.
Hub-centric rings do not correct an incompatible bolt pattern, incorrect lug hardware, or insufficient brake clearance.
Performance Tire Compatibility
The 8.5-inch wheel width accommodates a range of performance-oriented tire sizes.
Common tire widths considered for 8.5-inch wheels include:
225mm performance tires.
235mm performance tires.
245mm performance tires.
255mm performance tires, where approved by the tire manufacturer.
The correct tire size depends on the tire manufacturer's approved rim-width range, vehicle suspension configuration, overall tire diameter requirements, and available clearance.
Conical-Seat Lug Hardware Compatibility
The Konig Hypergram requires compatible conical-seat lug hardware.
Properly matched lug nuts or bolts are essential for safe wheel installation.
Before mounting, verify the required lug seat profile, vehicle thread size, and necessary thread engagement.
Factory lug hardware may not be compatible with aftermarket wheels.
Tire Pressure Monitoring System Compatibility
The Hypergram supports compatible tire pressure monitoring system (TPMS) sensors.
Vehicles originally equipped with TPMS may require transferring compatible sensors from the factory wheels or installing replacement sensors.
Sensor compatibility and programming requirements vary by vehicle.
Wheel Load Rating
The Hypergram is designed for performance-oriented applications and carries a manufacturer-specified load rating.
Before installation, verify the current load rating for HG8851445G and ensure that it meets the vehicle's applicable axle load requirements.
Brake Clearance Considerations
The Hypergram features an open 12-spoke design developed with performance-oriented applications in mind.
Its spoke arrangement may accommodate various factory and aftermarket brake systems.
However, compatibility depends on the specific brake system, rotor dimensions, wheel barrel profile, and spoke clearance.
Always verify brake clearance using an appropriate manufacturer-approved brake template before purchasing.
Matte Grey Finish Care
The Matte Grey finish should be maintained using cleaning products suitable for matte-painted aluminum wheels.
Avoid harsh acidic cleaners, abrasive polishing compounds, and aggressive brushes that may damage or alter the finish.
Regular cleaning helps remove brake dust, road grime, and other contaminants while preserving the wheel's appearance.
Matte finishes should not be polished with conventional gloss-enhancing compounds, as these products may create uneven or shiny areas.
