Why did tires start saving energy?

Do you know what rolling resistance is?

The answer is in the phrase itself. It is the combination of forces that act on the tire and prevent it from moving forward. Overcoming these forces requires energy, and in a car, energy is taken from only one place - the fuel tank. At the same time, the fuel consumption spent on overcoming the rolling resistance of the tires can sometimes reach up to 25%. In essence, a quarter of your fuel tank is constantly spent on tires.

It's no wonder that one of the main goals of tire manufacturers has long been to reduce rolling resistance. Moreover, solving this problem will lead to several advantages at once.

- lower fuel consumption for vehicles with internal combustion engines. Agree that spending not 25% of fuel on tires, but 15% will already be a significant advantage.

- less CO2 emissions. This is a consequence of the point above. The less fuel burns, the less emissions into the atmosphere.

- longer mileage for electric vehicles. This advantage is even more significant than the first, because refueling with gasoline is money, and recharging an electric vehicle's battery is money and time. At the same time, electric vehicle manufacturers simply will not allow the installation of tires with high rolling resistance on the primary equipment, and will strongly not recommend tires for replacement as they wear out.

Often it may seem that ecology comes first for so-called "eco-tires", but this is only an illusion. In fact, this is a question of the main competitive advantage in the next 10 years, because if you believe the automakers, by 2030, 80% of the vehicle fleet will be fully converted to electric motors.
