Wider rear wheels and tires are often installed on rear-drive performance cars because they provide more grip for acceleration and hard cornering. Wider rubber and rims also have aesthetic benefits because they give a car a more aggressive look. Among cars that have wider rear wheels and tires are the Chevrolet Corvette, Ford Mustang Boss 302, Nissan 370Z and BMW M3 to name a few, and all have rear-wheel drive.
BMW says mounting wider rear tires and wheels on a car like the M3 makes them harder to spin in hard acceleration, sacrificing tire-smoking burnouts in favor of better traction. In addition, a wider tire can withstand greater lateral forces in turns and maintain traction longer than a narrower tire.
Besides, wider wheels and tires “just look cool,” BMW spokesman Dave Buchko says.
