Precision-machined fitments, high load capacities, and verified structural integrity for sports cars, luxury SUVs, and commercial 4x4 platforms.
Combining raw material access, 10,000-ton forging presses, and 5-axis CNC machining centers to deliver unmatched strength-to-weight ratios and rapid OEM development cycles.
Unlike conventional casting where molten alloy cools with irregular crystalline structures and potential micro-porosity, our 20x10 forged wheel blanks undergo multi-directional forging under 10,000 metric tons of hydraulic pressure. This aligns the continuous grain boundaries of 6061-T6 aluminum strictly with the radial spoke geometries, drastically enhancing tensile resilience, ductility, and dynamic fatigue threshold.
Located in China’s premier manufacturing corridor (Kunshan, Jiangsu), our facility utilizes high-speed automated 5-axis CNC machining cells. The 20x10 specification requires precise caliper sweep clearances and back-pad pocketing to accommodate large multi-piston performance brake kits (Brembo, Akebono, AP Racing). We configure PCDs (from 5x112, 5x120, to 6x139.7) and offsets (ET-24 to ET+45) with micrometric tolerances.
Yield strength is not merely forged; it is heat-treated. Blanks undergo a computer-monitored T6 solution treatment at 530°C followed by high-velocity water quenching and precision artificial aging at 175°C. This cycle locks the intermetallic precipitates (Mg2Si) within the aluminum matrix, achieving typical Brinell hardness ratings exceeding 95 HB while maintaining structural elasticity during severe dynamic curb impacts.
Navigating electric vehicle curb mass, high-torque drivetrain demands, and sustainable aerospace-grade alloy procurement across North America, Europe, and the Middle East.
Electric vehicles (Tesla Model S Plaid, Lucid Air, Porsche Taycan) demand wheels capable of transferring up to 1,400 Nm of instantaneous wheel torque while supporting 2.5-ton vehicle weights. Our 20x10 forged rims provide reinforced bead-seat knurling to eliminate tire slippage under full acceleration launches.
Using advanced Finite Element Analysis (FEA) and topology optimization algorithms, our R&D engineering center eliminates non-load-bearing mass. This reduces rotational moment of inertia by up to 22%, yielding measurable gains in electric vehicle range (WLTP) and braking distances.
We utilize certified low-carbon recycled aluminum billets smelted using renewable hydro-power in upstream Chinese refineries. All machining swarf and aluminum curls are recycled into secondary closed-loop alloys, shrinking Scope 3 carbon emissions for global corporate procurement.
To safeguard enterprise distributors against overstocked inventories, Shanghai Rimax operates hybrid FCL and LCL shipping models. Distributors can mix cast, flow-formed, monoblock forged, and modular 2-piece / 3-piece rims in single shipments directly from our Kunshan facility.
The 20x10 inch wheel width represents the gold standard for wide-track footprint stability, aggressive concave styling, and high-performance tire bead engagement.
Fitment Setup: Staggered rear setups (e.g., 20x9 front, 20x10 rear) for BMW M3/M4/M5 (5x112), Mercedes-AMG C63/E63 (5x112), and Audi RS6/RS7.
Technical Need: Deep concave spoke profiles that maximize inner barrel clearance for carbon-ceramic braking assemblies while delivering optimum lateral grip during high-speed cornering load transfers.
Fitment Setup: Square 20x10 configurations for Porsche Cayenne, Range Rover Sport, BMW X5M/X6M, and Lamborghini Urus (5x130, 5x120, 5x112).
Technical Need: Load ratings exceeding 900kg per wheel. The monoblock forging structure prevents rim lip deformation when driving over potholes at high speed while running low-profile tires (275/40R20 or 295/40R20).
Fitment Setup: 20x10 negative offset (ET-12 to ET-24) with 6x139.7 and 5x150 PCD for Toyota Land Cruiser, Lexus GX460/GX470, Ford F-150 Raptor, and RAM 1500.
Technical Need: High impact thresholds tested according to 13-degree and 30-degree drop standards. Resists shock loads in rock-crawling, desert pre-running, and extreme off-camber overland expeditions.

How Shanghai Rimax Industry Co., Ltd. protects brand equity and ensures seamless customs clearing across overseas import territories.
Every production batch undergoes dynamic radial fatigue, dynamic cornering fatigue, and 13° / 30° impact testing on calibrated servo benches. Zero cracks or instantaneous loss of tire pressure are permitted under JWL / VIA / SAE criteria.
Finishes—including diamond-cut tinted clear, brushed translucent candy red, physical vapor deposition (PVD), and ceramic clear coats—undergo 720-hour accelerated copper-accelerated acetic acid salt spray (CASS) corrosion checks per ASTM B117 standards.
We maintain a laser-scanned 3D CAD library of brake caliper sweeps and suspension geometry for modern chassis. This ensures the 20x10 fitment clears control arms and outer fender wells without requiring aftermarket wheel spacers or body modifications.
We supply private-label buyers with custom CNC aluminum center caps, embossed rim lip laser inscriptions, barcoded corrugated export cartons, and fitted inner protective foam rings configured to survive trans-oceanic shipping.
Founded in 2010, Rimax is a verified alloy wheel manufacturer and exporter headquartered in Kunshan, Jiangsu, China. Supplying low-pressure cast, flow-formed, monoblock forged, and multi-piece wheels to premier automotive distributors in over 45 countries with an uncompromised 5-year structural warranty.
Direct answers to core technical inquiries from wheel brand owners, commercial buyers, and technical fitment engineers.
A 20x10 forged wheel machined from a 10,000-ton 6061-T6 aluminum blank has an ultimate tensile strength exceeding 310 MPa, compared to approximately 205 MPa for A356.2 low-pressure cast wheels. This allows our design team to mill thinner spokes and a sleeker barrel profile while increasing structural load ratings to 950 kg – 1,150 kg per corner. The result is a 20-30% reduction in unsprung rotational weight, which improves throttle response, suspension recovery, and thermal heat dissipation from heavy braking.
Yes. Because forged wheels are individually CNC-machined from solid round forging blanks rather than molded in fixed tooling cavities, we can customize bolt patterns (5-lug, 6-lug, center lock), center bore hubs (hub-centric down to ±0.02 mm), and offsets (ET) from negative 30 to positive 50. This flexibility allows distributors to offer bespoke fitments for exotic sports cars, tuned track vehicles, and lifted off-road trucks with minimal prototype turnaround time.
Every Kipardo forged wheel manufactured by Shanghai Rimax Industry Co., Ltd. is verified according to the stringent standards of JWL (Japan Light Alloy Wheel), VIA, and SAE J2530. QA documentation includes raw material spectroscopic chemical analysis, ultrasonic flaw detection, 3D coordinate-measuring machine (CMM) dimensional reports, dynamic cornering/radial fatigue test reports, and 720-hour salt spray corrosion reports.
For custom monoblock 6061-T6 forged wheels, our factory offers a flexible minimum order quantity of just 4 pieces (1 vehicle set) for bespoke private commissions, and 20 to 60 pieces for volume private-label container distribution programs. Prototype CNC engineering and sample finishing are completed within 15–18 days, with full commercial container production running 30–35 days from approved CAD drawings.
Every wheel engineered in our Kipardo manufacturing facility carries a 5-year / 100,000 km structural integrity warranty covering metal fatigue, spoke cracking, and inner barrel separation under normal driving and trail use. Additionally, our multi-stage electro-deposition, powder coat, and liquid lacquer finishes are backed by a comprehensive 2-year warranty against peeling, blistering, and surface discoloration.
