Technology leads the market, products serve customers

The tire force and ground contact pressure simulation optimization, with contour and material distribution of each part adjusted, balance force on each part of the tire and prevent abnormal wear caused by uneven rigidity of the block;

The optimized pattern noise simulation , with the adjusted pitch size and pattern blocks arrangement, enables the tread peak noise distribution at different frequencies, noise energy  dispersed so as to achieve the ideal silence effect.

Pattern optimization design

E200 displays an asymmetrical pattern, with wide inside grooves designed for drainage, reinforced outside blocks improving steering support. Characteristics of heavy weight and large torque of electric vehicles, shoulder block key ensure a maximum steering grip and ground contact area.

Four wide main grooves provide quick drainage, anti-aquaplaning and excellent wet skid resistance.

The noise dispersion control technology combined with various pitch is adopted to disperse noise . The closed lateral groove of the outer shoulder is designed to block the noise lateral diffusion in the main groove, reducing noise generation bringing a quiet and comfortable driving experience.

Load force simulation optimization

The high tensile belt steel wire and double-layer nylon reinforcement layer in the tread improve the the tread  rigidity, counterbalancing the deformation force caused by the high torque of electric vehicles, buffering the impact to the  tire, improving the driving and braking performance ensuring excellent durability and anti-wear properties.

Pressure distribution technology, ensure balanced forces on tire tread during driving, reducing the tread deformation and  heat generation, facilitating energy-saving, so that tire service life can extend.

Ground pressure simulation optimization

Tread compound applying new multi-terminal modified solution polystyrene butadiene of low rolling resistance , reduces energy loss on the tread, bringing ideal low rolling resistance performance and wear resistance performance.  High percentage of silica and high amount of resin are acquired to provide excellent wet grip.

Experimental data shows that E200 products, developed for electric vehicles reaches a rolling resistance level of the EU label A, which is 20% higher than conventional tires, by which cruising range is increased by about 3%.
