Tyre Inflation Advice

Check type pressure on a regular basis. The ideal pressure should be written on the inside of the driver’s door. Else, check the glove box, bonnet or owner’s manual.


Underinflated tyres lead to faster and uneven wear on the tyre surface. They also cause greater resistance on the road, meaning more energy and fuel are needed to keep the car moving. Fuel costs money, but checking and adjusting the tyres takes very little time.


Higher temperatures cause gasses to expand. This includes the air inside tyres. In hot conditions, or if you expect the wheels to get hot due to long periods on the road, it can be better to slightly underinflate the tyres. Stop to check if in doubt.


If you are carrying a heavy load or towing a vehicle you many do well to adjust the tyre pressure. A few caravan owners recommend increasing tyre pressure on the towing vehicle by 28Kpa/4psi, more for 4WDs.  Other inflate the back tyres slightly more than the front.


Underinflating tyres can help in some situations. If a vehicle is travelling on a beach or struggling with similar soft ground, then underinflated tyres can help traction.
