The TRX Style 2 wheels were developed for select BMW models, notably the E24, E28, E32, and E34 series, during the 1980s and early 1990s. These wheels are part of the Michelin TRX system, which was revolutionary at the time for its radial tire design. The TRX wheels are unique because they do not conform to the standard inch-based sizing; instead, they feature millimeter dimensions, with the TRX Style 2 wheels typically measuring 390 mm in diameter.
The design of these wheels is characterized by a sleek, multi-spoke pattern that was both functional and aesthetically refined. This multi-spoke arrangement not only contributed to the wheel’s strength and lightweight properties but also enhanced airflow for better cooling of the braking system. This was particularly important for high-performance BMW models of that era, which demanded superior braking performance during spirited driving. The wheel’s clean lines, subtle curvature, and symmetry were designed to blend seamlessly with the overall aesthetic of BMW’s vehicles, emphasizing the blend of luxury and performance that these models represented.
The TRX system, including the TRX Style 2 wheels, was known for its innovative approach to tire and wheel technology, though it eventually fell out of favor due to its non-standard sizing, which made it difficult to source replacement tires. Despite this, the TRX wheels are highly sought after by BMW purists and collectors today, particularly those who value originality and period-correct restorations of classic BMW models. For many, these wheels represent a unique chapter in automotive design, where innovation and aesthetics were closely intertwined.
Moreover, the TRX Style 2 wheels were typically paired with Michelin TRX tires, which offered a unique combination of performance and comfort, particularly suited to long-distance touring. The wheels contributed to a smooth ride while maintaining the sporty handling characteristics that BMWs are known for, particularly on the Autobahn or winding European roads where these cars were often tested to their limits.
Today, the TRX Style 2 wheels remain a significant part of BMW’s rich history, admired by enthusiasts for their blend of technical innovation, design integrity, and their role in defining the brand’s performance image during a transformative period in automotive history. They are especially prized for restorations, as they maintain the authenticity of some of BMW’s most iconic models from the late 20th century.
