The availability of disc brakes helped spur the introduction of the Rallye wheel, as the five oval-shaped slots offered cooling for new brake system. Additionally, it provided a sporty appearance, compared to full wheel covers of the past. In 1967, the Chevy Rallye wheel was offered in three sizes: 14x5 for Chevy II, 14x6 for Camaro and Chevelle and 15x6 for Corvette.
Chevrolet continued to offer the wheel on various models until the 1980's. By the end of its run, the Rallye Wheel had been produced in many sizes and backspacing configurations, based on its intended use. For instance, a 15x6-inch Chevy Rallye was available in various backspacing, one specifically for the 1967-1968 Camaro Z28 and another that fit several applications.
The early 1980's saw the end of the Chevy Rallye wheel on production cars, but Chevrolet continued to offer new replacement wheels for many years. You could order them at your local Chevrolet dealership.
