How Tyre Pressure Impacts Your Car’s Performance

Performance vehicles are detailed machines. Technicians spend thousands of hours fine tuning settings, changing features, and testing variations to optimise their performance. To extract performance from a car is a lot like an experimental scientist’s work. You play around, take record of the impact, analyse, and adapt.

This is also true when it comes to extracting performance from tyres. Many factors impact one’s ability to reach the end goal; keeping the tyre in contact with the road. The more contact a tyre sustains with the road, the more control the car has.

Each aspect of your car’s tyre impacts its overall performance to some extent. From the size and width to the type of rubber compound used in its construction. One cannot control many aspects of the tyre. Other than choosing the tyre you want, there is one aspect you can control; the pressure of your tyre.

Tyre pressure plays a vital role in how your tyre and car performs. In this article, we delve into why tyre pressure impacts your car’s performance, what the optimum tyre pressure is, and if you should adjust it.

Why Tyre Pressure Affects Your Car’s Performance

Having the correct tyre pressure ensures that your tyre performs at its peak in the right conditions. Each day’s weather and the location in which you are driving can affect your tyre in different ways. In other words, it could impact performance.

Tyres can be inflated with oxygen (air) or nitrogen. The most common choice is oxygen, as one can find it at most local filling stations. Oxygen molecules change depending on conditions like temperature and height above sea level.

Heat causes molecules to move faster, meaning the volume atoms take up increases. If you inflate your tyres with air, there is a great chance that the tyre pressure might change by the season. Its pressure can also change depending on whether the tyre is heated or cooled when it is inflated with air. Temperatures may be cooler when driving at slower city speeds compared to faster highway speeds.

Some people believe Nitrogen is a more stable option. They prefer to inflate their tyres using only nitrogen. There are a few things to consider about nitrogen before using it. Nitrogen is only 3% lighter than oxygen, but there's only 22% oxygen in air, meaning the difference in the weight from all four of the tyres is 0.3664 grams.

The Correct Tyre Pressure

As we realised, the air we put into our tyre changes. The change in oxygen is not the only thing to consider. We should also think about what we want the tyre to do in order to extract the most performance from it.

Tyre compounds are made from rubber and other materials, depending on the tyre type and manufacturer. Tyre compounds are designed to move, change, and mould the rubber to best fit the surface. Remember, the goal is to keep the tyre in contact with the road. This means that each scenario requires an optimum tyre pressure.

The Conclusion

The technicality of tyre technology ensures that road cars today don’t have to make any adjustments as it would meet the requirements for everyday use.
