Why autumn is treacherous
Two phenomena combine: the rubber stays cold (less grip) and pressure drops mechanically (roughly -0.1 bar for every -10°C). Add wet roads and fallen leaves, and morning grip bears no resemblance to a summer afternoon.
Pressure: check more often Check pressure when cold, in the morning. In autumn, reassess every week: a pressure drop of 0.3 bar degrades handling and accelerates wear. Stick to manufacturer specifications as your reference and don't improvise.
## Warmup: the first kilometres A cold tyre doesn't deliver its nominal grip. During the first 10-15 minutes:
- Avoid sharp angles and hard braking.
- Bring the temperature up gradually (light weaving, no aggressive steering lock on open road in cold conditions).
- Watch out for shaded wet patches and fallen leaves (grip is virtually non-existent).
