Tyres need proper inflation pressure to operate effectively and perform as intended. Tyres carry the vehicle, passenger, and cargo loads and transmit the braking, acceleration, and turning forces. The vehicle manufacturer recommends the inflation pressures for the tyres mounted on your vehicle.
Driving on tyres with improper inflation pressure is dangerous.
- Under-inflation causes excessive tyre heat build-up and internal structural damage.
- Over-inflation makes it more likely for tyres to be cut, punctured, or broken by sudden impact.
These situations can cause a tyre failure, even at a later date, which could lead to serious personal injury or death. Consult the vehicle tyre information placard and/or owner’s manual for the recommended inflation pressures.
In addition to tyre damage, improper inflation pressure may also:
- Adversely affect vehicle ride and handling.
- Reduce tyre tread wear.
- Affect fuel economy.
Therefore, follow these important recommendations for tyre and vehicle safety, mileage, and economy:
- Always keep the vehicle manufacturer’s recommended inflation pressure in all your tyres, including inside duals.
- Check their pressure at preventative maintenance intervals and during pre-trip vehicle inspections.
