What is the Importance of Tyre Pressure?
The most thought some people give to tyres is when they either get a puncture, or when they get a shock when the garage (or worse the police) tell them they need replacing. It's amazing how this important vehicle component can be so overlooked by so many people, but it's even worse when it comes down to the pressures in those tyres. Let's be totally honest here, some people never check their tyre pressure unless something is quite obviously wrong with one or more of them. There are two things not having the correct pressure in your tyres can cost you, which are money, and the safety of you and your passengers. So, let's take a brief look at how the incorrect pressure can affect your vehicle, and how some level of tyre maintenance really is vital to your overall car safety.
What's the correct pressure?
There's no hard and fast rule for what is the correct tyre pressure across the board. You need to find out what the correct pressure is for the particular tyres you have on your vehicle by consulting the owner's manual, by speaking to the dealer you bought your vehicle from, or through a tyre specialist. The amount of pressure required may also vary depending on whether you’re carrying a full load or not. Once again, find out from a reliable source how much pressure you should be maintaining in your tyres.
If someone is going to notice they have the wrong pressure in their tyres, it's usually going to be because they're underinflated rather than overinflated as it's more obvious. Underinflated tyres will make uneven contact with the road surface that will inevitably result in uneven and excessive wear at the edges if not corrected through a regular car maintenance regime. Under inflation can also result in an increase of rolling resistance with the road, and that will make your vehicle use more fuel and therefore reduce its efficiency and cost you money. But the worst result of underinflated tyres is poor handling, which can then lead to accidents, especially at higher speeds.
A lot of people don't realize it, but putting too much air in tyres can be just as problematic as not having enough in them. Overinflated tyres will have less surface area making contact with the road surface, which means less traction and longer breaking distances. It can also lead to uneven and excessive wear across the middle of the tyre, which means you'll have to replace them sooner than you would have had to if they'd been kept properly inflated.
Checking your tyre pressure
You should check your tyres around every two weeks, although more pressure is lost during warmer weather so you might want to check a little more often than that during the summer. Another thing to remember is that you should always check your pressure when the tyres are cold to obtain an accurate reading, as the pressure will increase when the tyres are hot and they're designed and manufactured to cope with that. And finally, keep in mind that some manufacturers will recommend different pressures for the front and rear, so make sure you're one hundred percent sure what the correct pressures are for your particular vehicle.For more information about your tyres and their correct pressures, don’t hesitate to get in touch with our experts here at the Kearys Motor Group
