How Under Inflated Tyres Impact Your Vehicle's Performance?

04 09,2024


Have you ever wondered why you need to always keep your tyres adequately inflated? You must have as every driver or vehicle thinks about the same. There is no one answer to this question. Multiple benefits of optimum tyre pressure make it essential to ensure your vehicle does not have over-inflated or under inflated tyres. From your safety to the vehicle's performance, several reasons mandate correct tyre inflation. But what if you do not maintain the right tyre pressure?

Under inflation of tyres is a common issue that must be avoided. Hence, Vredestein presents this exclusive guide that will brief about what under inflated tyres affect. Knowing about the negative impacts of deficit tyre pressure on your vehicle's performance will keep you motivated to regularly check tyre pressure and maintain an optimum level for your safety and your vehicle's performance.


What is Underlying Inflation?

Before jumping on to learning about its impacts, let's first get acquainted with what is underlying inflation. The tyre pressure of a tyre can be defined as one of the following categories. 

  • Under Inflation

  • Over Inflation 

  • Recommended Inflation

Under inflation of tyres refers to the tyre pressure that is below the recommended level. Underlying inflation can cause several issues for you and your vehicle. This is why experts suggest that the inflation level should always be maintained. Continue reading the next section of this blog, which lists all the impacts of underinflation.

Consequences of Under Inflated Tyres

Below are some of the many negative impacts of under inflated tyres. 


Uneven Tyre Wear

One of the first effects of under-inflation is on the sidewalls of a tyre. Low tyre pressure can cause the sidewalls to bulge out due to a lack of internal air pressure. As a result, the tyre fails to hold its correct shape. Bulged-out sidewalls of tyres can result in the edges of the tyre tread wearing out more quickly than they normally do after being in contact with the roads. If such a condition of a tyre is not noticed for long or ignored, it can lead to excessive wear. Eventually, the uneven wear can lead to tyre bursts from areas where the rubber gets too thin and becomes inadequate to hold the pressure. 

If and when you notice the unusual shape of your vehicle's tyres or notice any bulges or distortions in them, you must visit a garage for a solution. Experts will take proper care of the tyres to bring them back to their original shape. They might also replace your tyre if the wear is too severe. That is why you must regularly check your tyres and keep an eye out for any damage or unusual shapes.


Increased Fuel Consumption

Another problem that under inflated tyres can cause is enhanced fuel consumption. The condition of your tyres significantly affects your vehicle's fuel consumption. Therefore, they must be in good condition to ensure they do not consume excessive fuel. Low-pressure tyres result in poor fuel economy. They increase the rolling resistance, leading to more work for the engine to maintain the same speed. As a result, the fuel consumption of your vehicle will increase. So, do under inflated tyres waste fuel? Yes, they do, and you must maintain the correct tyre pressure to save money and the environment. 


Poor Steering Performance

In an unpressurised or less-pressurised state, the rubber of the tyres has more slack in it. The increased slack impacts your steering performance. This will make it a sluggisher than before. This is why steering will take more of a side-to-side turn when turning the tyres. If you do not maintain the recommended tyre pressure, controlling and steering your vehicle becomes much more difficult. Also, it will be challenging to control your car at high speeds. 


Shorter Lifespan

Tyres are a significant investment for your vehicle. Replacing them every now and then is not feasible. High-quality tyres require you to buy them at significant amounts. However, tyre lifespan reduces if you do not maintain optimum tyre pressure and drive your vehicle on under inflated tyres. Studies show that reduced tyre pressure can reduce the tread life by 25% to 30%.

Causes of Under Inflation

Underinflation is not just a natural process for tyres. Tyres can definitely lose pressure after running for a while. However, inflation can also be caused due to the following reasons. 

  • Hitting potholes and driving on other rough surfaces

  • Naturally, losing air pressure

  • A cut by a sharp object like a screw or nail

  • Corroded alloy wheel, resulting in poor sealing of the tyre

  • Poorly sealed valve

  • Tyre pressure can also be affected in colder months when the temperature drops.


In the End

Tyres are an integral part of your vehicle, no matter what type it is. Their condition significantly impacts the performance of your vehicle. Therefore, to maintain the performance and comfort of your vehicles, you must ensure the optimum condition of the tyres. One crucial aspect of maintaining their condition is tyre pressure. Tyres must be adequately inflated at all times. Maintaining the recommended inflation level ensures your safety on the road, convenience, comfort, and high performance for your vehicle. The above mentioned information must explain how underinflated tyres can be a threat to your vehicle's performance. So, no matter how high-quality tyres you buy from trusted manufacturers like Vredestein, regular pressure inspection for the tyres is a must. You should also know which tyre pressure your car tyre should have.


Frequently Asked Questions 


What is underlying inflation? 

Underlying inflation refers to the tyre pressure that is below the recommended level. Low tyre pressure can result in several problems, ranging from reduced vehicle control to severe accidents. Therefore, under-inflation of tyres must always be avoided. 


Why can under inflated tyres be dangerous? 

Underinflated tyres can severely impact your safety on the road. Such tyres reduce your control over a vehicle. They also increase the chances of sudden tyre bursts.
