How F1 drivers manage tyre degradation

Two kinds of degradation

Not all tyre wear is the same, and the type dictates how a driver manages it^[1]:

• Thermal degradation: the tyre overheats, the surface gives up grip, and lap time falls away even though there is rubber left. This is the dominant limit at hot, high-energy circuits.
• Mechanical wear: the rubber physically wears down over a long stint until there is little tread left.
• Surface problems: graining (rolled-up rubber on a cold or sliding tyre) and blistering (overheating from the inside) both cost grip and can be triggered by pushing too hard at the wrong moment.

What the driver does

A driver has real control over how fast a tyre fades^[2]:

• Stay in the window. Keep the tyre in its target temperature range; too cold and it grains, too hot and it overheats.
• Smooth inputs. Every slide, lockup, and bit of wheelspin scrubs grip and heat into the surface, so a clean, smooth lap saves the tyre.
• Lift and coast. Easing off before braking zones drops temperature and saves fuel and tyre. See lift and coast.
• Manage the high-load corners. A few tenths surrendered through the corner that hurts a given tyre most can buy several laps of extra life.

What the team does

:::analysis The pit wall manages degradation at a different level. Compound choice sets the starting point: a softer tyre is faster but fades sooner, a harder tyre is slower but lasts. Stop timing then turns tyre life into track position, because a driver who has saved their tyres can either extend the stint to change the strategy entirely or push hard at the end on rubber that still has life. Friday long runs exist almost entirely to calibrate the degradation model the strategists will trust on Sunday, and the team that reads its own deg most accurately can commit to an aggressive plan that rivals cannot. :::

Why it decides races

Degradation is the clock every strategy runs against. A car that is gentle on its tyres can make a one-stop work where rivals need two, or keep enough life in hand to launch an undercut or defend to the flag^[1]. On high-degradation circuits, managing the tyre is often worth more than outright one-lap pace.
