In truck transportation, tire tread patterns not only determine the vehicle’s grip and driving stability but also directly affect wear resistance, fuel efficiency, and overall operating costs. One key indicator in this regard is “tread void ratio” — the proportion of raised tread blocks to the total contact area with the ground.Tread Saturation ExplainedFormula:(Total Tread Block Area ÷ Total Contact Area) × 100%High Saturation: More rubber in contact with the road, typically offering better wea
