Tire Tread Block Width Variation for Snow Discharge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tire designs with block patterns for snowy roads enhance traction but fall short in drainage performance.
Innovation Solution
A tire tread design featuring blocks with varying widths in the tire axial direction, where one part protrudes more than the other, forming unevenness for improved traction and snow discharge, while maintaining balanced drainage and wear resistance through specific shape and protrusion configurations.

Engineering Contradiction Analysis
1Reliability
If blocks with varying widths are used to improve snow discharge, then on-snow performance is enhanced, but manufacturing complexity increases
Solution Approach 1:
The invention changes the width parameter of the block along the tire axial direction, creating two distinct parts with different widths. This parameter variation is implemented in a systematic way that maintains manufacturing feasibility while achieving improved snow discharge capability through the protruding second part.

AI summary
A tire 1 comprises a tread portion 2 provided with a plurality of blocks 5 arranged therein. The blocks 5 include at least one first block 20 comprising a first part 6 arranged on one side in a tire circumferential direction and a second part 7 arranged on the other side in the tire circumferential direction. The first part 6 extends in the tire circumferential direction with a substantially constant width (Wa) in a tire axial direction. The second part 7 has a width (Wb) in the tire axial direction larger than that of the first part 6 so that the second part 7 protrudes axially outwardly from the first part 6 so as to protrude more toward one side in the tire axial direction.
