Maintenance · Expert tip
Check tire pressure cold, monthly
Pressure drops ~0.1 bar per 10 °C — check cold for accuracy.
The expert tip
- Measure before driving (cold)
- Use the door-sticker pressure, not the tire wall
- Under-inflation costs 2–3% fuel and overheats the tire
- Check monthly and before long trips
