Our tyre pressure tool covers the majority of vehicles that have been nominated as appropriate by the vehicle manufacturer. You'll need to check that your car's tyre size matches the above before inflating your tyres to the recommended pressures. If your tyre size isn't included in the results, then that tyre size mightn't be suitable for your vehicle. Either way, your best bet is to check with the manufacturer of your vehicle, or consult with a reputable tyre dealer.
There's a couple of steps involved:
This tool is based upon the best data currently available. While data is available for most light vehicles (weighing less than 3.5 tonnes) manufactured from about 2000, the data coverage for vehicles built before 2000 is more limited. As more data becomes available, this tool will be updated.
Our tool has tyre pressure information associated with a range of tyre sizes for the majority of those vehicles.
If tyre pressure is not yet available for your vehicle, the correct tyre pressure for your vehicle can usually be found on a plate located on the driver's door, inside the fuel filler flap or in your vehicle handbook.
These are all ways of measuring units of pressure: pounds per square inch (PSI); kilopascals (kPa) and bars (no abbreviation). It doesn't matter which unit of pressure you follow to check your tyre pressure, as long as you are consistent across all your tyres, and that this is consistent with the tyre pressure gauge you're using.
Best bet is to increase your tyre pressure in line with the vehicle manufacturer's recommendations. If your vehicle handbook doesn't have this information, a rule of thumb is to add 4psi (28kpa or 0.28bar) to the recommended pressure.
Yes, it does. It is a safety risk to over or under-inflate your tyres. Overinflating tyres can adversely affect vehicle manoeuvrability, make the ride harsher, and sometimes lead to loss of control and crashes. Underinflating tyres can result in tyre stress due to overheating, irregular wear of tread, tyre failure, and sometimes loss of driver control and crashes.
We've worked with EECA (Energy Efficiency and Conservation Authority) to make every effort to provide accurate tyre size and pressure information. However, the accuracy of the data cannot be guaranteed and you should consult your vehicle handbook, talk to your local garage or tyre specialist if you have any doubts about the information contained in this tool.
