Tyre pressures should be checked every week or two and a simple reminder is to do it when you fill up your petrol. Some drivers keep a tyre pressure gauge in their glovebox as the gauges at the service stations can be inaccurate.
Having low tyre pressures will affect your steering, making it heavier and or pulling to one side. Fuel efficiency is also lowered as the rolling friction is increased. Driving on under inflated tyres will also decrease the life of your tyres.
It is best to check your tyres when they're cold as the pressure is different when the tyres are hot. To find out what pressures your tyres should be have a look at the tyre placard which is normally inside the either of the front door jambs. It will also be in the vehicle’s owner’s manual. Other factors that effect tyre pressure include ambient temperature, ambient air pressure (at sea level or high in the mountains) and the load in the vehicle.
Depending on the vehicle, some will have different pressures between the front and rear tyres. Tyres on the same side of the vehicle will always be identical.
While you’re checking the pressures, inspect the tread pattern to make sure its not worn and have a look at the sidewalls to make sure there aren’t any cracks, gouges or bulges. This is especially so on the passenger side as we are all guilty of hitting the kerb at times. If there is any damage to the sidewalls, contact your local A Grade Automotive Network workshop straight away.
Make sure you put the valve caps back on and don’t forget the spare tyre – out of sight shouldn’t be out of mind.
