Based on this blog post written by MICHAEL BORDA it seems like 100% of heat energy generated during sliding gets absorbed by tires. Like SPASKIS pointed out in the thread, that doesn't seem right. For example here (2nd page) it was estimated that 64% of the heat caused by slip between tyre and asphalt, would get absorbed by the tire. Not the best examble but still something. Then quotes from the blog: "The third variable, is the most important change, and allows us to specify the fraction of sliding power applied to the tyre as heat energy. On dry asphalt, this should generally be 1.0 or at least within 10% of that." "The third variable simply tells us how much of the sliding power should be applied to tire heat. Originally (and now by default), all of the sliding heat energy is applied." So my wish is that, if there actually is a mistake in how much of the heat energy from sliding gets absorbed by the tires, the mistake would be fixed. Or if there is no mistake, it would be nice to hear what i'm getting wrong.
