Tyre Pressure


One of the simplest – and most important – things you can do to keep your tyres in good shape is to make sure that they are properly inflated.

Failure to maintain correct tyre pressures may result in fast and uneven treadwear, improper vehicle handling and excessive heat build-up which could result in tyre failure.

Quick Summary

  • To find the recommended tyre pressure for your tyres, look in the vehicle owner’s manual, on the drivers side door jamb or in the glove box.
  • When buying new tyres, be sure to ask about the tyre pressure from your dealer. When you buy tyres from Woonona Tyres, we’ll be happy to go over the recommended pressure with you.
  • Air pressure can naturally decrease over use so regular checks should be made. The best time for checking air pressure is before long distance driving or at least once a fortnight.
  • Ideally, tyre pressure should be measured when tyres are cold – that is, before doing any driving on the tyres.
  • It’s important to be accurate when filling your tyres. Don’t try to “eyeball” the pressure – a tyre can lose half its pressure without looking flat.

Check Tyre Pressure Regularly

You should check your tyres’ pressure at least once a month (some even say every two weeks), before each trip, and each morning you drive during a trip.

Ideally, tyre pressure should be measures when tyres are cold – that is, before doing any driving on the tyres. Otherwise, your tyres may have heated and increasing the air pressure inside them by several pounds.

Measuring Tyre Pressure

It is important to be accurate when filling your tyres. Don’t try to “eyeball” the pressure – a tyre can lose half its pressure without looking flat. Instead, use a reliable tyre pressure gauge. It’s also a good idea to have your own gauge.

Under-Inflation

If your vehicle’s tyres are under-inflated by as little as 6 psi, it could lead to tyre damage. Additionally, the tyre’s tread life could be reduced significantly with tyres wearing more on the outside shoulders. Fuel economy is also affected by under-inflation – your vehicle has to work harder. Remember, any kind of uneven wear will shorten the lifespan of your tyres.

Over-Inflation

Over-inflation causes tyres to wear in the centre of the tyre’s tread which will reduce the tread life. Higher inflated tyres also give you a harsher ride, and as little as 6 psi over-inflation can cause more damage when hitting potholes or road debris. Remember, any kind of uneven wear will shorten the lifespan of your tyres.
