Regularly check your tyre pressure
Studies of tyre safety show that maintaining proper tyre pressure, observing tyre and vehicle load limits and inspecting tyres for cuts, slashes, and other irregularities are the most important things you can do to avoid tyre failure, such as tread separation or blowouts and flat tyres.
These actions, along with other care and maintenance activities, can also:
- Improve vehicle handling
- Help protect you and others from avoidable breakdowns and accidents
- Improve fuel economy
- Increase the life of your tyres
The importance of the correct pressure cannot be over-emphasised.
- Check tyre pressure, including the spare, once a week or before undertaking a long journey – or before 10 km have been driven.
- Check tyre pressure early morning (low ambient temperature)
- Always use a reliable pressure gauge
- Only use tyre sizes recommended by the manufacturers at the recommended inflation pressure
If the pressure is too low it affects the tyre in a number of ways
As speed rises, excessive contact patch deformation leads to a wave being formed in the tread, which generates excessive heat, causing structural damage or even tyre failure.
The extra flexibility will affect steering behaviour, directional stability, durability and rolling resistance. Even occasional low pressure driving, or periodic vehicle overloading, may cause damage that only shows up much later as a blowout.
