How Tyres Can Help You Save Fuel
The condition and wear of your tyres can significantly impact your vehicle’s fuel consumption. In this blog, we’ll explore how tyres affect fuel economy and what you can do to improve your car’s fuel efficiency.
Can worn tyres increase fuel consumption?
When driving, tyres create rolling resistance, affecting the energy required to keep the car moving. If a car tyre is low on tread and grip, it will have a negative impact on the rolling resistance, and therefore more fuel is needed in order to keep the car moving.
Tyres can also have an impact on aerodynamics. If you’re using the wrong sized tyre, for example, if the tyre is too wide, then your tyre can create more drag. This results in higher fuel consumption for your vehicle, due to more power needed to drive the vehicle and offset the increased drag.
Does tyre pressure affect fuel consumption?
Underinflated and overinflated tyres are one of the key reasons for tyres having a negative impact on fuel efficiency. If your tyres aren’t inflated to the correct PSI, then you will experience more rolling resistance. This is due to the tyres deforming and creating more surface area in contact with the road.
Overinflated tyres can also increase rolling resistance because they’re less flexible, which can lead to an increase in car bounce when driving. Ensuring your tyre is inflated to the correct pressure will help reduce rolling resistance, and in turn, make your car more fuel efficient.

How much difference do tyres make to fuel efficiency?
Paying attention to the conditions of your tyres and ensuring they are inflated to the correct level can make a significant difference in your vehicle's fuel efficiency, and save you money on fuel. The difference in fuel efficiency can be up to 10%, so it’s crucial to have your tyres in great condition in order to get maximum fuel efficiency from your vehicle.

Factors that reduce rolling resistance
Tyre pressure
Underinflated tyres create more rolling resistance because they deform more ad create more surface area in contact with the road. This can also increase the rate of wear on your tyre, reducing the tread depth.
Tread depth
Tyres with more tread depth allow for increased grip on the road and therefore help prevent the tyre from skidding and using more fuel to move. The increased traction will therefore help improve fuel efficiency. We recommend having your tyres replaced once they reach 3mm of trade depth, as once your tread is lower than 3mm, you will notice a considerable drop off in grip and fuel efficiency.
Tyre type
Different types of tyres may have different fuel efficiency ratings. For example, premium tyres typically have a better rolling resistance than budget tyres, hence why they are usually more expensive, as they save money on fuel long term.
How to improve your car’s fuel efficiency with tyres
Inflate your tyres to the recommended pressure
To extend tyre life and improve fuel economy, ensure that your tyres are inflated to the correct pressure. You can find the correct tyre pressure for your vehicle in your manual, on the sticker inside the driver’s door, or by clicking the link below.

Choose the right tyre for your needs
If you want maximum fuel efficiency for your vehicle, Energy Saving tyres are the ideal option. These tyres have low rolling resistance and therefore reduce your fuel consumption. Energy Saving tyres also decrease your car's pollution levels, as with less fuel being used by your vehicle, fewer harmful emissions are being put into the air.

Ensure your tyres are aligned
Misaligned wheels can cause uneven wear across your tyres, leading to an increase in rolling resistance and a decrease in fuel economy. To have your tyre alignment checked at your local National Tyres branch, click the link below.
Tyre Alignment
Your car’s tyres have a significant impact on its fuel consumption. By ensuring that your tyres are inflated to the correct level, choosing the right tyre, and by having them aligned, you can improve your vehicle's fuel efficiency, and save money on fuel in the long term.
