Tread Patterns to Improve Tire Performance

Tire design to improve noise performance without compromising steering stability. The tread has a unique pattern with continuously touching axial grooves. The grooves have ends that align in the tire circumferential direction. This allows the grooves to continuously contact the road during driving, reducing impact fluctuations and pitch noise compared to conventional staggered groove layouts.

Tire with improved lateral grip on snow-covered roads without compromising dry grip. The tire has a tread pattern with longitudinal sipes aligned with the edges of the tread blocks. These sipes are narrow (less than 2mm wide) and deep (greater than 1mm) to bite into snow. They also close under load to maintain stiffness. The sipe angle aligns with the block to prevent deformation. The sipe density balances grip and noise. The tread material is winter-friendly to maintain flexibility on cold roads.

A tire tread pattern design that reduces tire noise without sacrificing grip. The pattern has alternating blocks and grooves arranged transversely along the tread. The blocks are shoulder blocks on the outside and a central block with deformed contours. The central block has a zigzag shape that surrounds the outer edge. This deformed shape reduces noise compared to a straight zigzag. The grooves separate the blocks and provide grip. The alternating blocks and grooves create a noise-reducing pattern that allows good traction.

All-season and winter tire tread patterns with serrated leading and trailing edges for improved traction and grip on snow and ice. The tread has symmetrically arranged block elements in the center and shoulders. The leading edges of some block elements have serrated ramps, while the trailing edges have curved convex domes. These serrated and domed features provide biting edges that enhance traction when the tire is accelerating or decelerating on snow or ice. The serrated leading edges create biting edges as the tire contacts the ground, while the curved trailing edges help the tire release from the surface without sticking.
