For your car to perform well on the road, the tyres will need to be in good condition. This means that the tread will need to be deep enough to distribute standing water away, and prevent aquaplaning. But it also means that the tyres will need to be inflated appropriately.
Why Correct Tyre Pressure is Essential for Road Safety
But exactly why do tyre and vehicle manufacturers insist on a specific tyre pressure? The number, usually expressed in pounds per square inch, is there to counteract the weight placed on the tyre from above by the vehicle. The tyre should have enough give to absorb small bumps in the road, and the rubber should spread slightly over the surface. This ensures that the tyre can grip the road, and push the vehicle onward as it rotates.
If the tyre is underinflated, then you’ll have less control over the vehicle. If the tyre is overinflated, on the other hand, then you’ll suffer a greater risk of a blowout.
How Tyre Pressure Affects Vehicle Performance
Tyre pressure doesn’t just influence how safe you’ll be in the vehicle, but how much performance you’ll be able to get from it. An expensive, high-performance vehicle will not perform to its potential if it isn’t fitted with the right tyres, and if those tyres aren’t inflated properly.
Tyre pressure will affect your fuel efficiency, stopping distance, and acceleration. When tyres are underinflated, the engine will need to work harder to get the tyres to move, and propel the vehicle forward.
Choosing Tyres for Optimal Safety and Performance
Cheap tyres tend to be a false economy. Look instead for tyres from a reputable manufacturer, that matches the vehicle you’re driving. You can buy tyres online and benefit from an enormous breadth of choices.
Practical Tips for Checking and Maintaining Tyre Pressure
Generally speaking, it’s a good idea to check the tyre pressure every week or so. This will allow you to spot punctures and get the problem corrected. You can do this using a paid-for machine at the local filling station, or you can do it yourself at home using the right pump or gauge. Check the manual for your car to establish what pressure you should be aiming for. Bear in mind, however, that if you’re travelling in a car that’s fully loaded, you’ll need to inflate the tyres a little more generously.
