Do you check the air pressure in your car tyres?


It’s a general rule of thumb that if one of the tyres on your car starts to look or feel flat, then you need to change that tyre ASAP or risk losing it; driving on a flat tyre can end up seriously damaging the tyre rim or the suspension in your car!

Along with avoiding damage to your car, keeping your tyres filled with the optimum air pressure has a number of benefits including improving your car’s fuel economy and improving the tyre’s performance, traction, and handling. Which makes it surprising that according to Canstar Blue research, only 50% of people check the air pressure in their tyres monthly. On top of this, 8% of the population don’t check their tyres at all, and rely on their service to check this.

Breaking it down by generation, the research found that a reassuring 59% of Baby Boomers will check that their tyres are good to go – perhaps they have learned from past flat-tyre experience! – 41% of Generation X will check their tyres, and only one third (32%) of Generation Y will make sure that their tyres are safe to drive on. Considering that Gen Y’s are (generally speaking) more likely to be involved in car accidents than their older counterparts, it’s definitely a wise idea for them to be taking every measure they can to make their car safer to drive!

It’s also important to know that as we go into the colder months, our tyres will need extra care as the colder temperature will cause the air inside them to contract. This means that your tyres could end up flat overnight. The general rule of thumb is that every change of 5-6 degrees corresponds to a change of 1-2PSI (pounds per square inch) in your tyres; but in some extreme cases the change can be as much as 3PSI per 5-6 degrees. Essentially, if the temperature drops, so will the pressure in your tyres. If the temperature rises, your tyres will fill up accordingly.

Remember – every set of tyres will have a different PSI requirement but that being said, the recommended PSI for most tyres will fall in the mid 30’s. If you’re unsure about the recommended PSI for your brand and model of tyre, check the website of your tyre retailer. Overall, it’s recommended that drivers check their tyre pressure at least once a month, or before any big trip involving long drives.
