Unleash Performance and Style with the Ohm Proton 18x8.5 Flow Formed Wheel

Elevate your vehicle's aesthetic and driving dynamics with the captivating Ohm Proton 18x8.5 flow-formed wheel. Designed for enthusiasts seeking a perfect blend of radiant style and enhanced performance, this wheel features a brilliant silver mirror face finish that demands attention, coupled with advanced construction for a superior driving experience.

Cutting-Edge Flow-Formed Manufacturing

The Proton wheel is meticulously crafted using innovative flow-formed aluminum technology. This advanced process involves forging the wheel's barrel under immense pressure, resulting in a denser, stronger, and significantly lighter wheel compared to conventional casting methods. This reduction in unsprung weight offers distinct performance advantages:

  • Improved Responsiveness: Experience quicker acceleration and more agile handling.
  • Enhanced Braking Efficiency: Reduced rotational mass contributes to shorter stopping distances.
  • Superior Ride Quality: Lighter wheels allow the suspension to work more effectively.

Radiant Design & Optimized Fitment

Showcasing the distinctive Proton style, this impressive 18-inch diameter, 8.5-inch wide wheel is finished in a radiant Silver with Mirror Face, providing a premium, reflective aesthetic that makes your vehicle truly stand out. Its precisely engineered specifications ensure an optimal fit for a wide array of modern vehicles:

  • Diameter: 18 inches
  • Width: 8.5 inches
  • Bolt Pattern: 5x114.3 (5x4.5 standard)
  • Offset: 30mm
  • Center Bore: 64.15mm
  • Load Rating: 2000 lbs (907 kg)

This setup is ideal for achieving a more aggressive stance and improved handling on many Japanese and American models, enhancing both visual appeal and on-road performance.

Unrivaled Durability & Comprehensive Warranty

Ohm wheels are engineered for enduring quality, and the Proton wheel is built to withstand the rigors of spirited driving and daily use. With a robust 2000 lbs load rating, it ensures reliability and longevity. For your complete peace of mind, each wheel is backed by a comprehensive Lifetime Structural Warranty and a One Year Finish Warranty.
