Tread Patterns for Enhanced Tire Performance

Tire tread design with reduced handling compromise between dry grip and aquaplaning resistance. The tread has extended tread ribs that are limited by circumferential grooves. This provides high rigidity and grip on dry roads while still absorbing and evacuating water for aquaplaning prevention. The extended ribs reduce the number of transverse grooves compared to traditional treads, which reduces softening and handling penalties. The circumferential grooves restrict rib width and spacing. This maintains rigidity while allowing water absorption through the ribs and additional circumferential grooves.

A pneumatic tire with a tread design that improves braking performance on wet surfaces without sacrificing aquaplaning resistance. The tread has circumferential ribs and circumferential grooves. The rib flank contour along the circumferential direction follows a parabolic shape. This allows the ribs to deform differently compared to traditional straight flank contours. This results in more even pressure distribution between the ribs when the tire is on the ground, improving braking traction on wet surfaces. The parabolic flank contour also avoids excessive tension buildup in the ribs that can lead to aquaplaning.

Tread design for high-speed radial tires that improves drainage, reduces aquaplaning, and provides wear resistance and low noise at high speeds. The tread has steeply angled V-shaped profiled elements in the central portion that extend into the shoulder regions. The profiled elements have fork-shaped features at the ends in the shoulder. Continuous inclined grooves connect the V's from center to shoulder. The steeply angled V's and grooves provide effective drainage and prevent aquaplaning. The fork-shaped features in the shoulder allow the V's to transition without disrupting the groove flow. The steep V's and inclined grooves provide a high positive profile for wear and noise reduction.

A tread pattern for tires that provides good wet traction, steering, wear, and noise while minimizing the number of circumferential divisions in the tread. The tread has diagonal ribs and grooves arranged in a specific sequence. The ribs and grooves have varying widths in the shoulder and center sections. This provides optimal performance in wet conditions, steering, wear, and noise compared to traditional tread designs with uniform rib widths. The diagonal ribs and grooves reduce the number of divisions needed, simplifying the tread pattern. The wider ribs in the shoulders enhance grip, while narrower ribs in the center provide rigidity. The ribs can end blindly in the shoulder or have a head. This diagonal rib arrangement improves wet traction, steering, wear, and noise compared to traditional tread designs with uniform rib widths.

Asymmetric tread pattern tire design that improves cornering and wear resistance on all road surfaces. The tire has a wide circumferential main groove off-center. The tread is divided into wider and narrower regions around the main groove. The negative (unloaded) tread width ratios are made equal in both regions. This optimizes grip and wear balance for cornering and uneven wear on dry, wet, snowy roads. The design features equal width transverse grooves between main groove and tread ends, matching side blocks widths, central block widths, and sipes in the wider region.

Pneumatic tire with annular siping around the tread surface that increases friction on low friction roads like ice and wet roads while maintaining pattern rigidity compared to linear siping. The annular siping surrounds the tread and prevents steering stability issues on dry roads caused by excessive linear siping. It provides higher friction on low friction surfaces by exerting edge and wiping effects around the circumference of the tire. The annular siping also helps prevent pattern rigidity reduction compared to linear siping that can occur with many parallel sipings.

A method for designing tire tread patterns that improve aquaplaning resistance. The method involves determining relationships between specific tread pattern features and the dynamic water lift force that can occur during aquaplaning. By analyzing test data on tread patterns and water lift, functional relationships are established between pattern parameters like groove depth, width, and spacing, and the dynamic water lift force.

A tire tread design with undercut walls that improves wear resistance and traction by allowing water to drain better. The tread blocks have walls that slope inwardly and connect to the circumferential grooves. As the tread wears, the undercut walls depart from the circumferential grooves and channel water into the transverse grooves, preventing standing water and improving drainage. This prevents hydroplaning and improves traction on wet roads as the tread wears down.

Design method for tire tread patterns that minimizes unwanted tire squeal while maintaining good traction and wear. The method involves balancing the number of tread elements in adjacent circumferential ribs to prevent unfavorable squeal when the tire contacts the road. By designing the tread with rib groupings having different numbers of elements, the ribs provide a pitch sequence that reduces single-frequency squeal. The method allows customizing tread patterns with specific spacing sequences for optimal noise and performance.

A tire tread profile design that allows reducing the maximum lateral force capacity of the tire while maintaining good handling and traction. The design limits the lateral force capacity by constraining the outermost portion of the tread outside the contact patch. This prevents excessive lateral forces from overloading the tire and promotes stability in vehicles with narrow track widths. The tread profile has a regular inner section for handling and traction, but the outer section tapers off and extends beyond the normal tire footprint. This limits the lateral forces that can be transferred beyond the normal contact patch. It allows reducing the maximum lateral force capacity while maintaining normal handling and traction performance.
