A tread design for winter tires that improves grip and handling on snow, ice, and bare road. The tread has a specific block arrangement with a unique shape and layout that enhances snow traction, provides better steering response, and reduces aquaplaning. The blocks have serrated edges, curved contours, and a zigzag pattern that grips and bites into snow and ice, while also providing channeling for water evacuation. The blocks are also arranged in a specific configuration to maximize contact patch size and pressure distribution on dry roads. This tread design improves winter tire performance without sacrificing summer tire characteristics.

A tire with improved snow traction compared to traditional tires. The tire has blocks with recesses extending across the ground contacting surface and the sidewall. The recesses have triangular openings on both the ground and sidewall surfaces. The sidewall opening terminates before reaching the groove bottom. This unique recess design allows snow to pack into the triangular openings and compact onto the ground contacting surface, enhancing traction on snow.

Non-pneumatic off-road tires for vehicles like utility terrain vehicles (UTVs) that have improved rut wander performance without sacrificing load capacity. The tires have characteristics like low camber thrust stiffness, specific tread shape, and reinforcement layout to prevent excessive steering inputs and wandering when driving over ruts. The low camber thrust helps avoid getting stuck in ruts. The tread has a narrower center section to widen the contact patch. The reinforcement ply has a gap in one wrap at the center to reduce stiffness. This allows the tire to follow the rut contour instead of getting stuck.

Tire with optimized snow performance and low rolling resistance by using specific narrow groove patterns in the shoulder and center regions. The shoulder has alternating linear/arc shaped narrow grooves, while the center has an angled narrow groove connected to the main groove and a separate narrow groove that extends circumferentially. This configuration improves snow traction without sacrificing rolling resistance by providing biting edges in the shoulder and center that enhance grip on snow while minimizing voids for reduced rolling resistance.

A tire tread design that provides good snow performance and steering stability simultaneously. The tread pattern has three-direction intersection points between the grooves that allow compacting snow in multiple directions. These points have bent edges with an optimal angle range of 40-85 degrees. This design ensures strong snow shear force without sacrificing block rigidity for steering stability.

Pneumatic tire design with improved uneven wear resistance and wet traction. The tire has specific features in the shoulder and center regions. The center land portion has multiple center lug grooves with blocks between them. The middle land portion has multiple middle lug grooves, blocks, a notch on the center groove side of each block, and a middle sipe extending from the notch to the shoulder side. This configuration helps prevent uneven wear and improves wet traction by providing interconnected sipes and lugs that can channel water and provide biting edges.

Two-wheeled vehicle tire for off-road use that provides stable traction and slide control on both soft and hard terrain. The tire has a tread with middle blocks between the equator and edge. The middle blocks have different radially outer surface areas. The smaller block has no sipe, while the larger block has at least one sipe. This configuration allows better traction on soft terrain by maximizing block contact area, while preventing excessive block deformation and maintaining stability on hard terrain by avoiding excessive sipe depth in the smaller block.

Adaptive tire pressure management system that optimizes tire pressure based on factors like weather, road conditions, and driving habits to enhance safety, efficiency, and performance. The system monitors tire pressure, receives data on conditions, determines optimal pressure, and commands the tire pressure control system to adjust. It can also proactively suggest tire pressure adjustments at specific locations during a trip. The system can also calculate tire pressure schemes for entire trips.

Rubber composition for tire treads that improves braking on icy roads and response on snowy roads. The composition contains a diene rubber and an aromatic resin with a liquid glass transition temperature (-100°C to 0°C) containing an aromatic vinyl compound like styrene. The liquid aromatic resin provides a balance of tire softness and rigidity that enhances both ice braking and snow response compared to solid aromatic resins or non-aromatic resins.

Optimizing vehicle mobility performance by individually controlling wheel slippage to maximize mobility on rough terrain. The technique involves estimating wheel mobility performance based on force and velocity, comparing to maximum, and finding optimal slippage for each wheel to operate at peak mobility. This allows tailored wheel control for best vehicle performance on uneven terrain.

Recommending appropriate items to a vehicle user based on their driving behavior to improve user satisfaction and engagement with the vehicle diagnosis system. The system analyzes the user's driving data over a period and identifies predetermined behaviors. It then determines items to recommend based on deviations from normal behavior. Only one item is presented with a message to the user. This prevents overwhelming them with multiple recommendations. The item is selected based on the user's memory of the behavior.

Tyre pressure plays a vital role in dynamic control over the vehicle and enhancing overall fuel efficiency by lowering rolling resistance and, as result, tractive effort. Excessive speeding causes traction loss, which is primary cause of accidents. Wet roads make driving more perilous, hence majority accidents occur during rainy season.

A pneumatic tire with improved wet and snow performance by optimizing the tread pattern. The tire has alternating pairs of asymmetrically inclined main grooves extending from the ground contact edge to the equator. These form staggered land portions extending from the equator to the ground. The innermost blocks in each land have notches opening to the main groove connections, improving drainage. This pattern provides enhanced snow traction, braking, and wet grip compared to traditional symmetrical treads.

A method for temporarily increasing traction of a vehicle's tires to improve handling in scenarios like getting stuck in snow or driving on ice. The method involves using a controllable suspension system with adjustable dampers and springs. By selectively stiffening the suspension components, the vehicle's contact with the ground is improved, providing better traction. This can be done automatically based on sensor inputs or manually by the driver. The adjustable suspension allows the vehicle to transition between normal handling for dry conditions and enhanced traction for low friction situations.

Estimating the coefficient of friction between a vehicle tire and the road surface even when the tire is not slipping. This allows continuous coefficient estimation without needing complex observers. The coefficient is adjusted based on time since the last slip event. When slipping, the coefficient is calculated conventionally from torque, speeds, etc. But when not slipping, the coefficient is adjusted at a rate that increases with time since slip. This provides a smooth transition between slip and non-slip conditions.

A tire with adjustable tread design to improve grip on different road conditions. The tire has multiple variable regions in the tread that can be changed between raised, flat, and concave shapes using adjustment units. This allows switching the tire's contact patch configuration based on the road surface. Raised shapes provide extra grip on muddy, snowy, or wet roads, while flat shapes reduce impact on smooth roads. Concave shapes improve adhesion on slick surfaces. The tire can adapt its tread shape to better match the road conditions for improved traction and handling versatility.

Tire with studs that protrude automatically based on temperature to improve traction on snow and ice without performance loss on dry roads. The studs have a shape memory alloy portion that deforms at low temperatures to extend out of the tire tread. This protrusion provides better grip on snow and ice without needing manual stud installation. At higher temperatures, the studs retract into the tread for normal road use. The studs also have features like grounding and hinge sections to manage their engagement with the road surface.
