AI Technical Summary
Existing all-season tires suffer from increased wear energy and uneven wear due to grooves that enhance local stiffness, leading to reduced breaking and steering performance, while also compromising water drainage and traction on wet and snowy surfaces.
A tire design with narrower grooves and recesses adjacent to the grooves to reduce local stiffness, allowing for improved decoupling of block portions, enhanced bending capability, and better water drainage, while maintaining performance on dry, wet, and snowy conditions.
The design reduces wear energy, improves water drainage, enhances traction, and maintains breaking and steering performance by locally reducing stiffness through recesses, resulting in a more uniform wear distribution and improved overall tire performance.
