Why does the diameter of the wheels vary back and forth in a supercar?

The beginning of tire history

As the tire has evolved over the last 100 years, its advances have been made in parallel with the development of cars. Since our beginning, many tire companies have contributed to tire innovation and enhanced true driving emotion while putting emphasis on the becoming one with the environment.

In 1888, Benz invented the first gasoline car equipped with unique metal tires covered with rubber and filled with air, resulting in the pneumatic tire. The public, which was accustomed to hard metal tires believed the pneumatic tire to be no less than revolutionary. Popular use of the pneumatic tire began in 1895 and it was featured in automobile race from Paris to Bordeaux. In 1910, the B.F. Goodrich Company invented longer life tires by adding carbon to the rubber.

The next step in the wheel evolution was the disc one, which bears more resemblance to the initial solid designs. As with many other things in our history, the change of was prompted by lower costs as the steel disc wheels were cheaper to make. The rim could be rolled out of a straight strip of metal, and the disc itself could be stamped from sheet metal in one easy motion.

The development of Ultra High Performance (UHP) tire increased the tire performance.

Driving performance increased with the development of the UHP tire, which boasts superior concerning, drivability and braking, in accordance with new development of tire technology.

The UHP tire is defined as tire with a rim diameter equal to or less than 16 inches. UHP tire provides superior braking performance and concerning performance at high speed.

After that, a tire company like Hankook developed an airless tire using a new type of material. The NPT (Non Pneumatic Tire) saves energy by reducing the production process by half. It can be reused and recycled.

Benefits by using low profile tires

Apart from doing wonders for the looks of your car, low profile tires offer greatly improved levels of handling and grip, especially in the dry. Your car will also brake much better, with a wider contact patch (the area of the tire in contact with the road) that provides greater traction than a conventional tire. Low profile tires will benefit your car’s cornering characteristics by being able to handle greater cornering forces (CF), and steering performance sees a marked improvement as well.
