The Importance of Checking Your Tyres

Driving instructors Havering tips: Checking your tyres is as important as checking your level of alertness and health conditions before driving your car on the road. Precise tyre pressure is very essential for a safe travel.

Remember that tyre pressure is a measurement of the air pressure inside each tyre of your car. It’s an essential aspect of car maintenance. Bear in mind at all time that an incorrect tyre pressure can affect the handling, safety and fuel economy of your car including the lifespan of your tyres.

The amount of air inside the tyre determines the tyre pressure. So, it’s just normal for this to reduce over time even if your tyre is in good condition, therefore you need to add air to your tyres from time to time in order to often keep them at the correct air pressure.

Remember that there are two units being used for air pressure measuring in the United Kingdom (UK). The first and probably the most common is the psi which is already old-fashioned. This acronym psi stands for “pounds per square inch.” It’s a measurement in pounds where you can read how much pressure is applied to every square inch of the wall of the tyre. The most common of this pressure is: 30psi.

The other unit of measurement is bar. This is called a metric unit. One bar means the pressure of the atmosphere at sea level. The most common tyre pressure in bar is 2.1bar. It is equivalent to 30psi.

The air pressure increases as you pump air into your tyre. Then the pressure decreases over time whilst the air just naturally escapes or when you intentionally let the air out of the tyre. Remember that carmakers have been advising drivers to adjust their tyre pressures according to the number of people on board your vehicle and how much luggage it is carrying.

Actually, this is something that many drivers overlook, and in so doing, they’re costing themselves hundreds of pounds every year whilst they’re compromising their vehicle’s performance.

However, in some circumstances such as driving on snow or mud, the under-inflated tyres or lower-than-normal air pressure could be an advantage. However, it’s important to make sure that your tyres have been inflated as per instruction by the tyre manufacturer.

Now the inquiry: Why is tyre pressure so important? It is because tyres are the only point of contact between your vehicle and the road. And there are two essential processes: (1.)  Steering (2.) Stopping. These processes are entirely dependent on the ability of the tyres to grip the road surface.

As the pressure of the tyres change, so too do their shape. So, remember that the overinflated tyres have a rounded profile which doesn’t have enough contact with the road. Whereas, the underinflated tyres have a slightly concave profile which means that the centre of the tyre , where most of the grip is on, isn’t any more contacting effectively with the road. So, this will increase the wear on the tyre’s sidewalls.

On the other hand, the fuel economy may be the least important aspect of your vehicle affected by tyre pressures, however, it’s also the one most likely to push many motorists into checking their tyres frequently. But very simply put, underinflated tyres make your car harder to turn and so they will cause the engine to consume more fuel.

Therefore, tyres need to be inflated to the correct air pressure for optimum fuel economy. Also remember their environmental implications –that a car with underinflated tyres is burning more fossil fuel, thus emits more harmful CO2.
