Definition
Tyre pressure is one of the most important — and most neglected — safety parameters. Wrong pressure increases consumption, shortens tyre life, lengthens braking distance and raises the blowout risk. The recommended pressure is on the driver's door pillar sticker or the fuel-cap flap.
Key facts
- Check pressure every 15 days or before a long trip, always with cold tyres.
- Inflate slightly when heavily loaded or driving at high motorway speeds.
- Low pressure heats the tyre and can cause a blowout.
- High pressure reduces contact patch and grip.
