Petrol prices have been constantly rising for the past few years and before the world makes the shift to electric vehicles, prices are probably going to rise even further. One way to get the most out of the fuel you use is to check your tyres are at the correct pressure.
It's fairly common sense: If your tyres are under inflated at all, it increases the rolling resistance on the road, and requires burning more fuel in order to maintain speeds. The U.S Department of Energy goes so far as to claim that every one psi drop in pressure is equal to a 0.3 per cent drop in fuel efficiency.
It also works the other way: Over-inflating your tyres can improve your mileage, but with a significant safety risk - over-inflating reduces the amount of surface area that comes in contact with the road, reducing friction and improving fuel economy. But at the same time, it also reduces the amount of tread in touch with the road, which reduces the car's grip to the bitumen and results in a less secure ride.
The best option is to check your tyres are set to the correct pressure. You can generally find your tyre's required pressure on a metal label on the inside of the driver's door. Using the recommended pressure offers the best balance between fuel efficiency and on-road safety. And while tyre manufacturers recommend checking your tyres weekly to ensure the optimum pressure on the roads, doing it even once a month can make a huge difference.
