Optimizing Tire Tread Patterns for Better Grip and Handling

Asymmetric tire pattern for electric vehicles that balances braking, grip, stability and wear on both dry and wet roads. The pattern has optimized fine grooves on the blocks to improve performance for electric vehicles. The grooves are arranged differently on the inner and outer tread regions. The inner tread has more pitches for wet grip, while the outer tread has fewer pitches for quieter ride and stability. This balances wet performance, comfort, stability and wear on both dry and wet roads.

A wear-resistant tire pattern with optimized groove geometry to improve traction, water drainage, and wear resistance. The pattern has three main grooves around the tire circumference: an outer zigzag groove, a stepped middle groove, and a linear inner groove. The stepped middle groove has a gradual change shape to prevent foreign matter accumulation. The inner middle block has a Z-shaped groove and a U-shaped groove that connect to the inner main groove via a steel sheet. This allows quick water drainage to improve wet traction. The groove geometry balances grip, drainage, and wear properties for improved tire performance.

A tire pattern with improved wet grip and wear resistance while maintaining low rolling resistance. The tire has a central wide rib flanked by symmetrical side blocks. The side blocks have circumferential grooves, shoulder thin grooves, and shoulder pattern blocks. Open shoulder transverse grooves separate the shoulder blocks. The shoulder blocks each have steel sheets with radians. This pattern provides a wiper-type flow groove in the middle block to quickly evacuate water. The radial steel sheets on the shoulders enhance wear resistance. The symmetrical layout reduces vibration and noise.

A tire tread pattern with enhanced 3-level sipe geometry that improves dry performance while maintaining wet/snow performance throughout the tire's life. The sipe design has hidden voids that mitigate the decrease in wet/snow grip during wear. The sipes have interference profiles and contact surfaces that allow rolling contact during dry conditions. This provides improved dry performance compared to conventional sipes that sacrifice dry grip for hidden voids. The contact surfaces prevent full sipe closure during wear, maintaining wet/snow performance.

Motorcycle tire with improved grip and wear characteristics for sport touring bikes. The tire has a unique tread pattern with circumferential grooves that extend for shorter distances compared to the full circumference. This provides additional bite points on the road for acceleration traction, especially in low friction conditions. The shorter grooves in the middle of the tread prevent excessive wear during straight line and shallow turn driving.

A method for designing tire tread patterns that reduces hydroplaning and improves traction in curve sections. The method involves analyzing hydroplaning performance in curves, extracting the optimal transverse groove angle, and using that angle to design the tire tread pattern. This tailors the tire tread to minimize hydroplaning and provide better grip in curves.

High-control low-noise pneumatic tire with improved steering, noise, and durability compared to conventional tires. The tire has a unique tread pattern design that uses features like notches, narrow grooves, and convex bulges. The inner shoulder block has notches between central grooves. The outer central block has narrow transverse grooves. The circumferential grooves have protrusions with specific sizes and spacing. This asymmetric pattern reduces noise, improves steering, and prevents water trapping. The bulges in the wider grooves disperse noise. The notches and narrow grooves control steering and prevent water buildup. The protrusions in the circumferential grooves reinforce and disperse noise.

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.

Tire with balanced grip, stability, and wear performance for racing applications. The tire has a tread with a continuous land section and small grooves extending axially less than 2.0mm. The grooves have edges in the land. Closest to the tire axis, the grooves are surrounded by adjacent small grooves arranged in a matrix. This configuration improves grip, stability, and wear compared to longer axial grooves or circferential-only small grooves.

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. These relationships can then be used to optimize tread design for reduced aquaplaning risk.

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.

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.

Asymmetric tire tread design with enhanced grip and reduced noise. The tread has an asymmetric pattern with raised elements that have small, shallow incisions opening onto the rolling surface. This pattern repeats along the circumference. The incisions have width less than 1 mm and depth of at least 3 mm. The tread design aims to provide improved grip compared to traditional tread patterns while also reducing road noise. The specific incision density and pattern layout is optimized for grip and noise reduction.

A tire tread design with blocks having internal transverse grooves that extend axially along the tread. The internal ends of these grooves are located within the blocks. At the internal ends, the grooves have a slope edge between the tread periphery and groove bottom. This internal block feature provides improved traction and handling by preventing snow and mud from packing into the blocks and improving block-to-block contact on dry surfaces.

A tread pattern for heavy-loaded pneumatic radial tires that improves wear resistance and traction compared to conventional patterns. The pattern has a unique rib shape with semi-grooves between the main grooves. The semi-grooves have specific dimensions to balance traction and wear. The semi-groove extension height is 5-15 mm to prevent excessive wear while still allowing good traction. The semi-groove width is 1-5 mm to improve traction without reducing block rigidity. This pattern prevents abnormal wear between ribs and at the shoulders compared to conventional patterns.

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.
