It is very important to maintain the right pressure in your car tyres but unfortunately, drivers tend to overlook this particular aspect quite a lot. Perhaps, they do this because they do not understand the critical role that such a factor plays in the overall performance of the car. Tyre pressure has significant implications on various aspects of a car starting from its fuel efficiency to road safety. In this blog, we will talk about how tyre pressure affects the overall safety of your vehicle as well as its fuel consumption thus playing a major role in your driving experience as such.

The fundamentals of tyre pressure

Tyre pressure is the amount of air that the tyres of your car contain. It is measured either in bar or PSI (pounds per square inch). Manufacturers usually provide recommendations for the pressure that your car tyres must have depending on the vehicle model. You will usually find it on a sticker on the side door on the driver’s side or in the user’s manual. This recommendation depends on the optimal balance between performance, efficiency, and safety of the vehicle in question. Both over-inflated and under-inflated tyres can contribute to suboptimal driving conditions that will increase the chances of mechanical issues and accidents thus increasing your running expenses.

The relation between fuel efficiency and tyre pressure

One of the most measurable and immediate effects of tyre pressure is the effect that it has on fuel consumption. If the tyres are underinflated, it can increase rolling resistance, while overinflated tyres can reduce traction. When the tyres are underinflated a greater part of the tyre’s surface gets in touch with the road which forces the engine to work harder to move the car forward. If the tyres are overinflated it can create uneven wear on the tyres and compromise their handling. When you maintain the tyre pressure recommended by the manufacturer you make sure that they are functioning at their best which will also help you make the most of your car’s MPG or miles per gallon.

The relation between safety and tyre pressure

Tyre pressure is just as important as far as road safety is concerned. Remember that both overinflated and underinflated tyres can lead to hazardous driving conditions. If the tyres are underinflated it might lead to overheating. If the tyres are overinflated it might lead to the risk of tyre punctures. Both these situations can also compromise the braking and handling of the car. If the tyres are inflated properly it will provide you with the best balance of control and traction thus ensuring that you can stop, maneuver, and steer your car effectively.

The effect on the longevity of tyres

Having the right pressure in your tyres also has a positive influence on the lifespan of your car tyres. If the tyres are overinflated they would be worn out unevenly. This would usually happen at the center of the tread. If the tyres are underinflated they will suffer too much wear on the edges. In both cases, the lifespan of your car tyres will be reduced and significantly so. This will also increase the frequency of replacements and the costs that you incur on them.

Ways to maintain the right tyre pressure

It is quite simple to make sure that your car’s tyres have the right pressure but it is an important aspect of maintaining a car. You can try a few tips in this regard such as checking the tyre pressure regularly, adjusting for weather conditions and load, inspecting for visible damage, and using high-quality air compressors. Use only a reliable tyre pressure gauge to check your car’s tyre pressure. You must also do this before every long trip and a minimum of once a month. If you are driving in extreme temperatures and/or carrying heavy loads adjust tyre pressure as per user manual recommendations.

You must always maintain the correct pressure in your car tyres but this is not a complicated task at all. Remember that doing so can have a profound impact on the road safety offered by your car and its levels of fuel consumption. So, when you make sure that the tyres of your car are inflated properly not only do you save on fuel expenses but also lower the chance of suffering from accidents and increase the lifespan of your car tyres. Regular adjustments and checks are keys in such cases.
