This configuration, frequently implemented on classic General Motors pickups, involves fitting wheels of different widths or diameters to the front and rear axles. Typically, wider and sometimes larger diameter wheels are installed at the rear to enhance traction and provide a more aggressive stance. For example, a classic truck might utilize 18-inch wheels with 9-inch width in the front and 20-inch wheels with 11-inch width in the rear.
The utilization of varying wheel sizes offers several advantages for vehicles modified for enhanced performance and aesthetics. It can improve handling characteristics by influencing weight distribution and tire contact patch. Additionally, this setup contributes significantly to the visual appeal, often resulting in a more muscular and purposeful appearance reminiscent of high-performance sports cars. Historically, hot rodders and custom car builders have employed similar techniques to optimize both form and function, adapting design principles from racing applications to street vehicles.
