UHP ALL SEASON TIRE

Small zigzag steel sheet design

The advanced tread rubber and the optimized layout design of the small serrated steel plates on the tread improve the vehicle's grip on light snow roads in winter, meeting the vehicle's use in all seasons.

Silent composite technology

The combination of the silent ribs at the bottom of the groove and the silent fine lines on the edge of the longitudinal groove effectively breaks the order frequency of the tire pattern and reduces the tire pattern noise

High saturation tread block design on the outside

Improve the ground contact performance of the outer side of the tire when the vehicle is turning at high speed, thereby improving turning stability and responsiveness.

Open streamlined pattern design on the inside

Enhance traction on wet roads or light snow, ensuring the vehicle's wet braking performance

Excellent anti-slip design

Three wide longitudinal grooves, designed to match the small zigzag grooves on the ribs, can effectively drain water and provide reliable anti-slip performance

Design of trench bottom diversion structure

Improve the tire's longitudinal groove wiper ability on slippery roads and improve the tire's outer side drainage performance

Eccentric wear warning design

Remind users whether the tires are unevenly worn, thus extending the service life of the tires
