Tyre noise ratings tell you how much sound your tyres produce on the road — a factor that affects both comfort and concentration while driving. This guide explains what those decibel numbers really mean, how noise levels are measured, and why choosing low-noise tyres can make every journey quieter, smoother, and more enjoyable.
There is no escaping the fact that cars are noisy. The combination of the engine and the revs behind the accelerator, the intermittent blast of a horn, squeaky brakes, and rolling wheels means that noise relating to vehicles is inescapable.
Of course, electric vehicles are growing steadily quieter. They no longer make the same start up noise, with the running of the engine a much smoother and quieter experience.
But still, the movement of tyres on the road surface creates some noise.
Which is why we thought it was important to create this article – not only reminding vehicle owners about the noises their car makes, but also drawing attention to the tyre noise rating and why it matters.
What is the Tyre Noise Rating?
Look at any fairly modern tyre and you will see that the labelling system depicts a tyre with a speaker next to it and a number indicating the decibels.
This is the tyre noise rating – in essence, a decibel reading that lets you know your tyre’s impact on local noise pollution.
A reading of one or two bars is considered within the acceptable range, while three bars is high.
In terms of figures, it is generally accepted than rolling tyre decibels sit between 67 and 77 decibels.
Why Does Tyre Noise Rating Matter?
From your position inside your vehicle, possibly with your music turned up loud or the radio on, you might be wondering why noise rating matters.
In fact, it is believed that a higher noise rating interrupts your concentration when driving and can lead to driver fatigue, as the noise leads to excess vibrations inside the vehicle. Even when you don’t realise it, the noise from your tyres is soaking into the cabin of your car through vibration and the friction of the rubber on the road surface and suspension.
So, not only does the tyre noise rating affect those outside your vehicle but it also has on effect on the comfort of you as the driver and your passengers.
