This invention relates to the field of tire technology and discloses a tire with low
rolling resistance, high handling, and low electrical resistance, comprising a first crown, a second crown fixedly connected to the bottom of the first crown, and a third crown fixedly connected to the bottom of the second crown. This invention, by setting up a first crown, a second crown, a third crown, and vertical grooves, utilizes the vertical grooves on the first crown to pierce the water film during wet driving, thereby improving drainage efficiency and grip. On dry surfaces, the groove edges increase
ground contact, enhancing handling response. Simultaneously, the groove distribution disrupts rolling
noise frequencies to reduce
noise, increases surface area to aid heat dissipation, buffers
peak pressure to improve wear uniformity, and works synergistically with the low
rolling resistance of the second crown and the electrical
conductivity of the third crown. Testing has verified that this structure allows the tire to maintain a higher level of grip performance and achieve a
rolling resistance coefficient reaching EU Class A.
