All You Need To Know About Tyre Rolling Resistance
If you’ve come across the phrase ‘tyre rolling resistance’ but know nothing about it, then you’re not alone. Most vehicle owners have no idea of what the phrase means, which is why we’re here to help you out with the same.
Before we get into the real concept of tyre rolling resistance, it’s crucial to start with an example first: when you ride a bicycle with under-inflated tyres, it becomes difficult to paddle. But, when you inflate the tyres to their original shape, it becomes easier to paddle. Such a concept is called rolling resistance.
What Do You Mean By Tyre Rolling Resistance?
Now that you’ve got an idea regarding what rolling resistance is, it’ll be easier for us to break down the scientific definition for you.
In a nutshell, rolling resistance is the amount of energy consumed by the tyres of a vehicle when it travels a specific distance. Thus, it’s the effort to keep the vehicle tyres rolling.
According to a reliable tyre shop in West Auckland, the rolling resistance of a tyre is one of the forces that tends to oppose the movement of the vehicle, along with other forces such as inertia, gravity and aerodynamic forces.
The Impact Of Rolling Resistance On Fuel Efficiency
As of the current day & age, tyre manufacturers and automakers have always emphasised that having low rolling resistance will lead to higher fuel efficiency.
It should be learned that almost 20 percent of your fuel consumption is spent on your tyres. And this is due to the rolling resistance of the vehicle tyres. More the rolling resistance, more fuel will be burnt. The current rule of thumb is that – a decrease in rolling resistance by 10 per cent will lead to a 1-2% enhancement in fuel efficiency.
You must know that each of the individual tyre components contributes to the rolling resistance phenomenon. These include the bead area, tread pattern, belt & sidewall package and so on. Some external factors that affect rolling resistance are air temperature, tyre inflation pressure and vehicle speed.
For instance, an inflated tyre will create less loss of energy and ultimately less fuel being burnt, due to less rolling resistance. The alternative is also possible. Such is the reason why it’s always recommended to maintain proper tyre pressure for your vehicle.
Is It Possible To Obtain A Tyre That Has Low Rolling Resistance And Increased Control On The Road?
Yes. While it may seem like an impossible combination – a tyre having greater control on the road while also having lower rolling resistance – but the truth is, the solution was founded way back in 1992 by tyre manufacturer Michelin.
The introduction of silica into the tyre manufacturing process is what made such a feature possible.
