We joke about the many reasons why NASCAR racing machines don’t have the same character as race cars from the 1980s and older did. They are silhouette racers, template cars at best. For a long time, four-door front-drive family sedans like the Toyota Camry and the Ford Taurus were the vehicles represented on the track, and you knew that based on the sticker packages that the cars were wearing at the time. Over the last couple of years, NASCAR has at least attempted to address some of the criticisms in certain areas. The Ford Taurus, Chevrolet Impala and Toyota Camry have given way to the Mustang, Camaro and Supra. The body shapes are starting to slightly resemble the production vehicle shapes…at least, in the nose cones. But one last bit of antiquity is going to become redundant in the next couple of years: the fifteen-inch wheel and tire combination.
