The Impact of Tyre Pressure on Vehicle Performance and Safety


Tyre pressure is a critical factor that influences the overall performance and safety of a vehicle. Maintaining the correct tyre pressure can enhance vehicle efficiency, prolong tyre life, and ensure safety on the road. If you are looking to get new car tyres in Singapore, or just want to extend the life of your current tyres, this article will help you understand the various impacts of tyre pressure on vehicle dynamics, including fuel efficiency, tyre wear, and handling characteristics.

Fuel Efficiency

One of the most noticeable effects of tyre pressure is on a vehicle’s fuel efficiency. Under-inflated tyres have a higher rolling resistance because more of the tyre’s surface area touches the road. This increased resistance means the engine has to work harder to move the vehicle, leading to higher fuel consumption. Studies have shown that for every 1 psi drop in the pressure of all four tyres, fuel efficiency can decrease by 0.2%. Maintaining optimal tyre pressure is a simple yet effective way to reduce fuel consumption and, consequently, lower greenhouse gas emissions.

Tyre Lifespan

Tyre pressure also significantly affects the lifespan of the tyres themselves. Both over-inflation and under-inflation can lead to premature wear. Under-inflated tyres tend to wear out the edges of the tread prematurely due to the increased contact with the road surface. Conversely, over-inflated tyres wear more in the center of the tread. Properly inflated tyres distribute stress evenly across the entire tread, which optimizes the lifespan of the tyre by preventing uneven wear patterns. Regularly checking and adjusting tyre pressure is essential to maximizing the life of the tyres.

Handling and Safety

The handling characteristics of a vehicle are largely dependent on tyre pressure. Correctly inflated tyres ensure that the vehicle has good traction and handling properties, which are crucial for safe driving. Under-inflated tyres can lead to decreased steering precision and longer braking distances, significantly increasing the risk of accidents, especially in wet conditions. Over-inflation, on the other hand, reduces the amount of tyre that can contact the road, which can lead to a loss of traction and an increased likelihood of tyre damage from road imperfections.

Risk of Blowouts

Driving with incorrect tyre pressure increases the risk of tyre failure, such as blowouts. Under-inflated tyres can overheat due to the excess friction with the road, while over-inflated tyres are more susceptible to damage from potholes or other debris on the road. Maintaining the correct pressure helps reduce these risks and ensures the structural integrity of the tyre.

Environmental Impact

Besides affecting vehicle performance and safety, tyre pressure has environmental implications. Proper tyre pressure optimization contributes to fuel efficiency and, by extension, to reduced carbon dioxide emissions. Moreover, ensuring tyres are properly inflated and thus extending their lifespan reduces waste and the need for frequent tyre production.
