The hotter the air is, the crazier the atoms will be, that being said, it will also change the humidity of the air itself, and since tires at high speeds will increase size due to rotational Gforces it would not be a stretch that some of the air will try to expand at the same time. That means that heat ends up moving into the inside of the tire, where it meets air. The single fact that tires hit the contact with the ground and create friction alone makes the temp of the patch to go up, the temperature will rise even more if the tire is trying to get a grip (drifting, steering, etc.) and, due to basic physics, temperature will try to radiate itself through anywhere it can.
Friction creates thermal energy (temperature) and tires are supposed to create friction between the wheels and the ground. Air pressure, humidity, and volume depends on temperature. Nevertheless, it helped to reduce the rolling resistance by about 3 times, and we relied on it for several years.Click to expand.Oh, you mean IRL?, well, the concept is basic. It also was difficult to calibrate correctly, as it behaved unpredictably and could become unstable if run at full strength. Internally we called it the “black box” due to how difficult it was to reason about. This elastic layer absorbed and re-emitted the collision energy back to the nodes when they lifted off again. A solid layer below and an elastic layer on top having a depth of a few mm. Our second attempt was to break the ground model into two parts. On the not-so-physically accurate side, we could have applied an additional torque to the wheel to compensate for the increased rolling resistance, but it would reduce the available grip of the tire even more, due to the increased propulsive demands being put on the tire. And anyways, the idea was also too expensive in computational cost. The net energy loss was the same, because although the nodes were lighter and took less energy to collide, there were more of them colliding. The first thing we tried to do was increase the number of tire nodes to make the tire “more continuous”.
