ECOSPORT X77-UHP/RACE-Powertrac-Powertrac Qingdao Uni-Power Tyre Co., Ltd

ECOSPORT X77

Extreme Performance formula

The optimized groove ratio, available in both 5-groove and 4-groove designs, is paired with an innovative raw material formulation and advanced mixing technology. This enhances the rigidity of the pattern blocks, improving tread grip, handling precision, and braking Performance. The result is a tire that offers higher driving limits and meets the demands of more advanced driving conditions.

Comfortable driving quality

Each specification adopts Al virtual analysis to simulate the working state of tyres under real road conditions, optimize the tread pitch arrangement, further eliminate unnecessary noise interference, and provide drivers and passengers with a more comfortable and quiet experience.

Exceptional dry land Performance

The outer tread features a high sea-to-land ratio, enhancing road contact for superior grip. Its multi-layer skeleton structure boosts support rigidity, minimizing tire deformation during cornering and steering. This design ensures optimal grip on dry roads, delivering precise and reliable handling.

Enhanced Safety in Wet Conditions

The optimized groove ratio design of the inner tread significantly boosts drainage efficiency on wet surfaces. Its spike-shaped chamfer design, combined with a linear steel sheet layout, effectively penetrates the water film. This ensures a safe and stable driving experience, offering reliable hardware support for secure travel.
