Tyre Air Pressure – What You Need To Know

Tyre air pressure should be regularly checked to ensure your  tyres are driving correctly and evenly. Checking your tyre pressure and making sure that it is ideal will help prevent the need for tyre repairs. Each car’s tyre pressure will be different and looking over the owner’s manual will help provide a clear guide. Here at Peninsula Auto Clinic, we offer professional tyre replacement and repair services where our trusted mechanics will complete a wide range of tyre services. 

Tyre air pressure means how much air is inside the tyre to ensure it wears evenly and grips onto the road correctly. Each tyre will have a different tyre pressure, or PSI (pounds-per-square-inch), which the manufacturer will recommend. Driving with an over-inflated or under-inflated tyre will often lead to wheel alignment and balancing problems and the chance of needing a tyre replacement and repair.

Tyre Air Pressure What You Need To Know

How Do I Check My Tyre’s Air Pressure?

It is important to check the inflation pressure of the tyres when they are cold. Allow the tyres to have rested for at least a few hours before checking the air pressure. This is because warmer tyres will have an inaccurate tyre pressure reading. 

The tyre air pressure should also be checked every two weeks to ensure tyre issues are avoided. If the tyres are under or over-inflated then this can be resolved before serious issues occur.

On the driver’s side of the car door or in the owner’s manual will be a recommended tyre pressure. To know more about the steps of checking the tyre air pressure we highly recommend reading our blog for further details here

How Do I Inflate or Deflate My tyre?

To either inflate or deflate a tyre to ensure that the air pressure is correct there are different ways to complete the job. To inflate the tyre local petrol stations will often have inflation machines or purchasing one can be done. Here are the steps to inflate a tyre and increase the air pressure:

  1. Remove the cap of the tyre valve and attach the machine to the valve
  2. Record what tyre pressure the tyre is at then set the machine to what PSI level is needed
  3. The machine will automatically pump the needed air into the tyre until the needed amount is reached
  4. Detach the machine, return the cap on the valve and repeat the tyre pressure check and inflation for each tyre

To deflate the tyre it requires constant checks of the tyre air pressure reading to ensure enough air is removed from the tyre. The best way to let some air out of the tyre to remove some air pressure is to:

  1. Remove the cap of the tyre valve and place a screwdriver or similar object over the top of the metal pin present
  2. Press the tool inwards to let air flow out through the valve stem
  3. Check the reading of the tyre air pressure to see if more air needs to be removed
  4. Repeat the process with the other tyres that may be over-inflated

We strongly recommend that a licensed mechanic or your tyre specialist performs the tyre inflation or deflation to ensure the job is done properly. The incorrect pressure could be read and the tyre might be over or under-inflated. A fully qualified mechanic will know the exact and correct tyre pressure and how to professionally adjust the pressure. 

Is it Bad to Drive with Over-Inflated or Under-Inflated Tyres?

  What Does it Mean Why is it Bad
Over-inflated Tyres Tyres wear more on the middle and the bottom will protrude out more. This will lead to the tyres having less contact with the road.  The tyres will handle worse when steering and brakingTyres squeak or make unusual noises The overall comfort of the drive is negatively impacted and often harsherWhen driving on wet roads the tyres are more stiff making the drive more dangerous 
Under-inflated Tyres The tyre will leave a larger contact with the road when they are under-inflated. There is wear on the sides of the tyre and the tyre curves at the bottom.  Rolling resistance is increasedThe car fuel economy and efficiency is impacted as the engine will have to work harderSteering response is negatively affected and the stability of turningThe tyre will often need to be replaced more quicklyThere is a chance that the tyres could dislodge off the rim when the car is turning

Another major issue with over and under-inflated tyres are wheel alignment and balancing issues. To know more about wheel balancing and wheel alignment and how the service to repair them goes, read our blog with more information.
