Why is checking your tyre pressure so important? 

The air pressure in the tyres supports the weight of your vehicle, so if it is low this can have a detrimental impact on the way that your vehicle runs. The main reasons that it is important to make sure that your tyres have the correct air pressure are; 

  • Safety: low tyre pressure will mean that your car struggles to steer and brake, meaning that your car is unable to react in an emergency situation. 
  • Economy: not only does having low tyre pressure wear your tyres down quicker, meaning that you will need to spend money on replacing them more frequently. It also means that your vehicle will be less fuel efficient, and you will be spending more money on fuel. 


How often should you check your tyre pressure?

It is best to check your tyre pressure monthly, this ensures that your vehicle is performing optimally. When your car goes to the mechanic for a service, they will check your tyre pressure as standard as well. This is the same frequency that you should be checking your tyre tread, these two can be checked easily and quickly together. 

Step 1 – Find out what the correct tyre pressure is for your car recommended by the vehicle manufacturer. Usually this information will be on a sticker on the driver’s side door frame, inside the fuel door or in the vehicle manual. If you are unable to find this, Genless has a helpful tool to check the correct tyre pressure for your vehicle. 

Step 2 – Check your tyre pressure, remove the cap from the nozzle on the tyre and push the air pump onto it. You should now see the current tyre pressure showing on the air pump screen. If the number is lower than the correct pressure for your vehicle, you will need to add some more air into the tyre. If the petrol station has an automatic air pump, you will not need to check the pressure. You can simply set the desired air pressure then attach the pump to the tyre nozzle and the machine will do the rest. 

Step 3 – If the tyre pressure is lower than the correct tyre pressure for your car, squeeze the air pump trigger in short bursts to inflate the tyre until it reaches the correct level. 

Step 4 – Once you have completed all above steps, replace the cap on the tyre nozzle and repeat for all other tyres.
