Tyres play a crucial role in a vehicle’s overall performance, from grip and handling to fuel efficiency.
One often overlooked but important factor is rolling resistance – a key element that affects how much energy is needed to keep your vehicle moving.
Understanding tyre rolling resistance can help you make informed decisions when choosing tyres, particularly if you are looking to improve fuel efficiency and reduce running costs.
In this guide, we will explain what rolling resistance is, how it impacts performance, and how to reduce it for a more efficient drive.
What is Rolling Resistance?
A tyre’s rolling resistance refers to the energy required to keep a tyre rolling at a consistent speed over a surface.
Every time a tyre rotates, it deforms and recovers as it comes into contact with the road.
This process leads to energy loss, known as hysteresis, which the vehicle’s engine must compensate for – resulting in higher fuel consumption..
Several factors contribute to rolling resistance, including:
- Tyre construction and technologies – The materials and tread design affect energy loss.
- Tyre pressure – Underinflated tyres create more resistance due to greater deformation.
- Road surface – Smoother roads reduce resistance, while rough surfaces increase it.
- Temperature – Cold weather can stiffen tyres, increasing resistance.
The more rolling resistance a tyre generates, the more effort is required to keep the vehicle moving – leading to higher fuel consumption and emissions.
