Car manufacturers actually have a tyre pressure chart on all new cars showing correct tyre pressure for the tyres the car came with.

There’s a few basics every car owner should know to keep their vehicle in tip top shape. Most people spend their time learning the inside of the engine bay -- how to check your oil, replace your water, or maybe check your brake and coolants fluids. But how many people check their tyre pressure regularly? The last thing you want when travelling at 100kmph down a busy highway is to have a tyre fail from being underinflated. Here’s everything you need to know to keep your tyres in tip top shape.

Car tyre pressure is a measurement of how much air your pneumatic tyre holds. Correct tyre pressure ensures the tyre wears evenly and continuously maintains the correct level of grip on the road. This is referred to a PSI, or pounds-per-square-inch.

Are all tyres created equal? Well, no. Different tyre manufacturers have different recommended tyre pressure, and different car brands will come with completely different tyre’s attached as standard. Not to mention, different dealers may offer different tyre brands for your model of car based on how you utilise your vehicle. For example, a BMW smash repairs in Sydney would have completely different tyre options than a Mercedes smash repairs would, a west ryde smash repairs would offer completely different tyre variants compared to a ryde smash repairs. It’s always smart to ring ahead of time to check the stock levels and brands available.

This is a good reference point when dealing with the original tyres a vehicle comes with, however you may have different tyres on your vehicle than comes as standard.


Driving with too low pressure can lead to a flat tyre, if not resolved immediately, the tyre could roll off the wheel, or cause the vehicle to have dangerously unresponsive handling performance, which would affect braking in an emergency.

If your tyres are over-inflated you’ll find they’ll wear a lot faster. Also your vehicle will harsher, and have a greater risk of blowing or skidding in more variable conditions. Every tyre is designed to work in an effective pressure range from low to high.

Checking tyre pressure is a simple task that even a complete novice should be able to accomplish. Simply pull into any decent service station and find the on-site air hose, then check the recommended tyre pressure for your particular tyres. If you can’t find the recommended tyre pressure, best to check which tyre brand you’re utilising and call a local dealership, mechanic, or local tyre shop.


In my local area I would search “smash repairs ryde”. I would then check to make sure they’re affiliated Audi approved repairers, as it’s always beneficial to make sure the dealer specialises in your car brand. I would then check they supply my tyre brand, and enquire if they had the correct tyre placard relevant to my tyres.

Once you’ve got the correct PSI for your tyres, remove the valve caps on your tyres, unroll the air hose, and firmly press the end of the hose onto the valve. Digital air pumps are the best way to monitor tyre pressure. These pumps will automatically inflate the tyre to the desired PSI. You may find analog manual valves at many service stations. Simply release the inflation lever once your desired PSI is reached on the gauge.

Lastly, always keep an eye on your spare tyre’s pressure. The last thing you want when you’re stranded on the side of a road is a spare tyre that’s also deflated.

Now that you’ve got your ear to the ground on proper tyre pressure -- you should have all the knowledge you need to never have your tyres fail again.
