Snow Traction Enhancement for Winter Tires

A specialized traction enhancement system for vehicles stuck on low-friction surfaces like ice, snow, mud, or sand. The system uses flexible strips with unique features like adhesive gripping elements, progressive elevation segments, and self-deploying connectors to automatically insert and position under tires. This allows the strips to self-feed into place using the wheel rotation, providing traction without needing precise placement or external force. The strips also have sensors to transmit weight distribution data.

Tire tread pattern with enhanced 3-level sipe geometry that improves dry performance while maintaining wet/snow traction throughout the tire's life. The sipe design has two key features: interference profiles and contact surfaces. The interference profiles are steps within the sipe that prevent full contact between adjacent sipe edges when the tire is new. This reduces stiffness and improves grip on wet/snow. As the sipe wears, the steps wear down allowing full contact for improved dry performance without sacrificing wet/snow traction. The contact surfaces are areas within the sipe that are meant to contact the ground during rolling. These provide additional voids in the tread for improved wet/snow grip as the sipe wears. The combination of interference profiles and contact surfaces allows optimized performance on both dry and wet/snow surfaces by compensating for void reduction during tire wear.

Tire tread compounding and design for improved wet grip and chipping resistance on snow and wet roads at low temperatures. The tread has a lateral groove with deep depth that drains water well. The rubber composition uses an isoprene-based rubber and styrene-butadiene rubber mix to dissipate energy and prevent chipping. The rubber compound has a silica filler with small particle size and a silane coupling agent to improve dispersibility. The tread thickness, lateral groove depth, and brittleness temperature are optimized to balance wet grip and chipping resistance.

Controlling the differential locking function of a vehicle like a farming tractor to improve traction on slippery terrain. The method involves detecting wheel slip, calculating the slip based on actual and acceptable wheel speeds, and tracking the trajectory where slip exceeded acceptance. This allows identifying areas where the ground conditions reduced traction. The differential can then be unlocked in those areas to prevent wheelspin. After leaving the slippery section, the differential can lock again for normal driving.

High-performance snow tire with improved grip on a variety of winter road conditions like snow, ice, and slush. The tire has an alternating pattern block and longitudinal groove layout. The pattern blocks are staggered left to right: left shoulder, left secondary, center, right secondary, right shoulder. Longitudinal grooves are between adjacent blocks. This configuration allows better snow and slush evacuation compared to traditional snow tire layouts. The alternating block and groove sequence improves traction on packed snow and slush, while the staggered blocks aid in snow shedding.

Tire tread design with sipes that maintain performance as the tire wears. The tread has sipes with three different depths, forming three levels in the tread blocks. The shallowest sipes are at the top level and the deepest sipes are at the bottom level. This allows the sipes to maintain their biting edges and void volume as the tread wears down, improving wet and snow traction over the life of the tire. The staggered depth levels also prevent damage or tearing when the mold is removed from the tread during manufacturing.

A tire design with improved traction on snow and ice without sacrificing wet performance. The tire has circumferential grooves and lugs like a typical tire but adds a narrow circumferential groove within one of the land areas. This narrow groove has bends and an inclination opposite to the main grooves. This creates a zigzag shape with long and short sections. The zigzag groove configuration allows increasing the total groove area to enhance snow traction while avoiding the reduction in land rigidity that hurts ice performance.
