Tires naturally generate heat as they roll, especially around the shoulder area—the thickest and least ventilated part. In standard tires, this heat builds up because there’s no good way for it to escape. Overheating here can cause tire damage like shoulder bulging, which reduces tire safety, performance, and lifespan. Current designs try to reduce heat using layered rubber materials, but these solutions either reduce durability or don’t allow for high wear resistance.
The Innovation
This new tire design introduces specially placed heat dissipation holes in the tire shoulder. These holes allow trapped heat to escape as the vehicle moves, using airflow to cool down the tire more effectively. There are two types of holes:
- First heat dissipation holes are level with the belt inside the tire.
- Second heat dissipation holes sit lower and are staggered for better airflow.
Both are carefully spaced and shaped to avoid exposing key tire components like internal cords or belts to air or damage.
What’s New
The key inventive step is the integration of airflow channels directly into the tire shoulder—precisely where heat builds up the most. Unlike previous approaches that rely on material tweaks, this design changes the tire’s structure to actively vent heat while preserving thick rubber layers for wear resistance.
Tangible Benefits
- Extends tire lifespan
- Improves safety by preventing overheating
- Maintains durability and grip even at high speeds
- Reduces maintenance and replacement costs
Broader Impact
This tire innovation could benefit the automotive industry by making tires safer and longer-lasting—especially for trucks, high-speed vehicles, and heavy-duty use. It may also reduce rubber waste and environmental impact by reducing how often tires need to be replaced.
