What tyre overheating actually is
A tyre makes its best grip in a narrow temperature window. Push past it and the rubber goes greasy, the surface grains or blisters, and every lap is slower than the last. Overheating is usually a symptom: too much pressure (the core builds heat), wrong camber (one edge takes all the load), or a balance that makes one axle do too much work.
The number that sets the window — see tyre pressures and the brake thermal window.
How the engineers diagnose it
Overheating is a symptom — the engineers trace it back to its cause:
- Pressure — the hot pressure is the readout. Too high and the centre of the tread overheats and the contact patch shrinks. Set cold so the tyre lands mid-window hot (a slick typically rises ~16–24%).
- Camber and edge temps — if the inner edge runs far hotter than the outer, there’s too much camber cooking that edge; if one axle runs hotter than the other, the balance is overworking that end.
- Workload and balance — an understeering car burns its fronts, an oversteering car its rears, a locked diff scrubs the rears on entry. Fix the balance and the temperatures follow.
Tyre temperature is where setup and strategy meet — a tyre kept in its window is grip you still have on lap twenty. One change, a full stint, read the thermal trace. See the glossary and the setup guide.
