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

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.
