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.

A pneumatic tire with heating elements in the longitudinal grooves to improve traction in snowy or icy conditions. The tire has a heating unit in each groove with graphene to convert tire rolling motion into electrical energy. A switch allows activating the heating elements when needed. The graphene stores electrical energy during normal driving and then releases it to heat the adjacent groove rubber when activated. This melts snow stuck in the grooves for better traction. The graphene-based heating system allows quick snow removal without relying on tire temperature.

Adaptive tire traction system for vehicles that enhances grip in all weather conditions without changing tires or adding chains. The system uses a curved composite tire with distinct rubber zones on the shoulders and center. The outer shoulder has studs for snow/ice, the center has low friction rubber for normal traction, and the inner shoulder has high grip rubber for emergency braking. The tire can tilt inward to engage the inner shoulder for better grip in emergencies, triggered by ABS sensors. This allows optimized traction without sacrificing fuel efficiency or tire life. The tilt mechanism can be hydraulic or connected to the ABS system.

An intelligent tire that is explosion-proof, low-carbon and environment-friendly, and can adapt to different road conditions. The tire has features like: 1. Explosion-proof: The tire can prevent bursting by using a protective cover over the tire beads, sensors to monitor bead integrity, and a self-sealing inner liner that patches punctures. 2. Low-carbon: The tire reduces carbon footprint by using a solid inner core instead of a pneumatic bladder, which eliminates the need for frequent replacement when worn. 3. Environment-friendly: The tire is environment-friendly by being reusable, as the inner core and tread can be swapped out when worn instead of replacing the whole tire. 4. Adaptive: The tire adapts to road conditions by using intelligent components that can change shape, like telescoping ant

Adaptive deformation tire with a controllable tread width to improve vehicle mobility on rough terrain without changing tires frequently. The tire has a tread, spokes, struts, sleeve, and main shaft. The spokes and struts are made of shape memory resin. They have through-holes with resistance wires. When power is applied, the wires heat the spokes, causing them to bend and deform the tread from wide to narrow for better traction on rough terrain. The tire can self-adjust width to adapt to different terrain.

Self-adaptive tire for sand pit muddy roads that transforms its structure in situ to improve grip and then reverts back to reduce rolling resistance on normal roads. The tire has spokes with heated sections that soften when warmed above a threshold temperature. When driving in mud, the spokes extend straight by turning off power. In mud, they cool and stay extended. On normal roads, power is on, heating the spokes to bend back. This allows the tire to dynamically morph between a straight configuration for mud and a bent configuration for normal roads using thermal stimulation.

Tire with deformable profile and a method to dynamically change its shape to optimize traction and generate electricity. The tire has an inner carcass surrounded by an outer carcass. Conductive elements on each carcass generate magnetic fields that repel or attract each other, changing the distance between the carcasses and effectively deforming the tire shape. This allows adjusting tire profile for better grip on varying surfaces. The deformation also increases friction between two friction layers inside the tire, generating electricity through friction.

This allows variably changing the widths of the grooves, cuffs, and sipe edges using electrical signals. It enables tailoring tread performance for different scenarios like wet vs dry vs snow by selectively widening/narrowing specific areas.
