How To Avoid Tyre Pressure Loss
Sudden tyre deflation can be caused by a drop in temperature overnight. And when tyre pressure is lost it can cause an excessive overload through overheating. This leads to steering issues and can be extremely dangerous. See how to avoid tyre pressure loss here…
Reasons for Tyre Pressure Loss
Even new tyres can experience pressure loss due to temperature change caused by the weather. And there are two main wheel issues that can also cause tyres to lose air slowly. These are:
A bent or damaged wheel
If you’ve hit an obstacle or your wheel has lost its shape due to corrosion air loss from the tyre can be increased. A bent wheel adds vibration. And damages the tyres beading. All leading to excess pressure loss.
Deteriorating valve stem
Valve stems can begin to leak air when they’re constantly exposed to roadway chemicals. Over-tightening of the valve cores can also add to the problem. The torque needs to be set at around four inches per pound.
Other Potential Tyre Damage Causes
Nails can puncture a tyre and cause air to leak quickly. If the nail stays in the tyre for a period of time it can cause air loss ongoing. And needs to be removed before the tyre becomes in need of urgent repair.
Debris between the sealing surface of the tyre rubber and metal can cause loss of air. And a loss of pressure. Seal breaking is related to cars of older age, as the rubber loses its elasticity due to weakness. The bead is sometimes fitted incorrectly causing the tyre to lose air slowly.
Driving over a large pothole or brushing against the kerb can cause cuts, punctures, and sidewall bulges. Both external and internal damage can result in air leak contribution and loss of tyre pressure.
Preventing Tyre Pressure Loss
Modern cars have a Tyre Pressure Monitoring System. But this may not take effect until the pressure loss becomes significant.
The BMW tyre pressure warning, for example, indicates that you need to drop speed to below 50mph, find a safe place to pull over. And stop the car. This BMW tyre pressure light is triggered by the pressure monitoring system built into the wheels.
You should aim to check your tyre pressures on a weekly basis. Use the specifications in the car’s owner manual to ensure the pressure is accurate. Tyres can easily lose pressure each month on a scale of one psi. And add another one psi for every five degrees Celsius of a drop in temperature.
Make sure the tyres are cold when you check them. If the car has been in the sun or you’ve recently driven the inflation rate won’t be accurate. Choose the most appropriate tyre gauge for you – this could be a dial, digital, or stick options.
If you find your tyres are losing more pressure still you should arrange for a tyre specialist to take a look. Tyres that are constantly underinflated can cause irregular tread. As they wear faster on their sides. Remember that tyre pressure is most important for the safety of you and your passengers.
Locating the Leak
Look at a selection of methods to source the air leak:
- Listen for a distinctive hissing sound
- Feel for a hot area on the tyre
- Apply a spray detergent mix to the tyre and rim – bubbles will appear where the leak is after about five minutes
- Remove the wheel and put it in water – the leaking part will release small bubbles
Stranded at the Roadside?
If you’ve been driving on underinflated tyres you may experience a dramatic blow-out. After you’ve recovered from the shock, you’ll need the help and experience of experts from professional car recovery services.
