Modern high-performance tires operate under demanding thermal conditions, with surface temperatures regularly reaching 80-100°C during aggressive driving and racing scenarios. These thermal loads affect compound properties, wear patterns, and ultimately tire performance—with every 10°C increase potentially reducing tire life by 20%.

The fundamental challenge lies in managing heat distribution across the tire structure while maintaining optimal temperature ranges for different compound zones and operating conditions.

This page brings together solutions from recent research—including dual-path liquid-gas circulation systems, integrated heat radiators with high thermal conductivity materials, self-adaptive cooling mechanisms, and solar-powered hybrid cooling approaches. These and other developments focus on practical implementation for both passenger vehicles and commercial trucks, addressing both steady-state and dynamic thermal management needs.

1. Dual-Path Liquid and Gas Circulation Tire Temperature Control System with Integrated Heat Exchanger and Compressor Modules

GREAT WALL MOTOR CO LTD, GREAT WALL MOTOR COMPANY LTD, 2023

Tire temperature control system for vehicles that provides efficient and automated tire heating and cooling to improve tire performance and safety in various conditions. The system uses both liquid and gas circulation paths to heat or cool the tires through dedicated modules. The tire temperature is monitored along with ambient temperature to determine when to activate heating or cooling. This allows proactive temperature control based on environment and tire conditions. The liquid path uses a heat exchanger to circulate fluid between the tires and a liquid treatment module. The gas path has a compressor to circulate gas between the tires and a gas treatment module. This dual-path system provides more flexibility and efficiency compared to relying solely on external heating or airflow cooling.

4. Vehicle Cooling System with Adaptive Airflow Path Control Mechanism

JAGUAR LAND ROVER LTD, 2022

Controlling the cooling system of a vehicle to optimize cooling performance and aerodynamics. The cooling system has a radiator and a directing mechanism to control the airflow path downstream.

The mechanism is mounted on the wheel hub and connected to the brake caliper. It has a detection chamber with balls, springs, and gears that sense tire temperature and a transmission chamber with rods and gears that control airflow. A flow disc with an eccentric hole drives a gear to regulate airflow through the shunt cavities in the wheel hubs. This allows air to be directed to the tires as needed to cool them during high-speed or heavy-load driving.

11. Hybrid Water-Cooled and Air-Cooled Tire Cooling System with Solar-Powered Controller and Evaporative Mist Mechanism

UNIV YANTAI, YANTAI UNIVERSITY, 2020

A hybrid water-cooled and air-cooled tire cooling system for trucks that leverages solar power to improve cooling efficiency. The system uses solar panels on the roof to generate electricity, a battery to store it, and a tire cooling controller to manage the water pump, fan, and mist nozzles. This allows converting the water-cooled system into a combined water-cooled and air-cooled system by misting the tires with high-pressure water. The mist evaporates to cool the tires, aided by the fan. This improves cooling compared to just water spraying. The solar panels power the system without needing an external power source.

13. Rotating Tire-Integrated Water Discharge System with Velocity-Responsive Valve Mechanism

SHANDONG HUAYU UNIV OF TECHNOLOGY, SHANDONG HUAYU UNIVERSITY OF TECHNOLOGY, 2019

A vehicle tire cooling system that automatically releases water from the tire to absorb heat and protect against damage from high road temperatures. The system has a water storage chamber around the tire that rotates with the tire. A valve in the chamber allows water to be discharged through the tire tread grooves. The valve closes when the car stops and opens as speed increases, automatically adjusting water flow based on vehicle velocity. The discharged water absorbs heat between the tire and road, reducing damage. When the tire is stationary, the valve is closed to prevent leakage.

14. Heat Exchanger Assembly for Internal Cooling of Pneumatic Tires

BRIDGESTONE AMERICAS TIRE OPERATIONS LLC, 2019

Cooling system for pneumatic tires to prevent internal heat buildup and tire failure at high speeds and loads. The system involves attaching a heat exchanger to the inside surface of the tire. Coolant flows through the exchanger inlets and outlets. The exchanger absorbs heat from the tire interior as the tire flexes and transfers it to the coolant. This coolant can then be circulated externally to a pump attached to the wheel rim. The pump rotates with the wheel and provides continuous cooling. The coolant can be circulated internally or externally, depending on the configuration.

15. Pneumatic Tire with Internal Coolant Circulation Unit and Heat Dissipation Structure

Nexen Tire Corporation, 2019

Pneumatic tire with an internal cooling system to reduce internal temperatures and prevent delamination. The tire has a coolant circulation unit inside the tread and/or shoulder that circulates a cooling fluid. The circulation unit is bent and may have a protruding heat dissipation part. This closed loop cooling system prevents peeling by lowering internal temperatures when the tire is hot. It prevents cracking by keeping the coolant completely enclosed.

16. Coaxial Impeller and Liquid Nitrogen Spray System for Tire Cooling in Wheel Well Assembly

Zhejiang Leapmotor Technology Co., Ltd., 2019

An automobile tire cooling device to prevent tires from overheating during driving, especially in hot weather. The device mounts inside the wheel well and uses a blowing impeller to directly cool the tires. It also has spray nozzles with liquid nitrogen to further cool the tires. A temperature sensor triggers the nitrogen spray when needed. The impeller and driving impeller are coaxially connected, with the driving impeller outside the wheel well. This allows the blowing impeller to directly face the tires. The device connects to a liquid nitrogen tank and ECU for control.

17. Axle-Mounted Heat Exchanger System Utilizing Vehicle Refrigeration for Tire Temperature Regulation

Mand Electronics and Appliances Co., Ltd., 2019

Tire cooling system for cars that reduces tire temperatures without adding weight or water tanks. The system uses the car's refrigeration system to cool tires. A compressor, condenser, throttle, and heat exchanger connected to the refrigerant lines are added. The heat exchanger is mounted on the axle. When the compressor runs, it chills the refrigerant. The throttle reduces pressure. The cooled refrigerant flows through the axle heat exchanger to absorb heat. Spokes connect the axle and wheels, allowing heat transfer. The cooled axle then transfers heat to the tires. This smart system intelligently cools tires using the car's AC instead of adding weight and water.
