How do old tires sound?
The loud rolling noise of tires is often associated with what is colloquially referred to as «sawtooth» — irregular tire wear. So if you notice strong, loud tire noises when rolling, tires are usually worn out irregularly, so that in the worst case you have to dispose of them.
Are new tires louder at first?
If new tires make noise, that’s not necessarily a cause for concern. In general, tires with a higher load index are louder, which is why you should only have tires with a higher load index fitted for good reasons.
Why are my summer tires so loud?
Uneven tire wear leads to loud rolling noises in passenger cars and motorcycles — this phenomenon is known under the term sawtooth formation. This guide provides information about the causes and consequences of saw teeth on the tire as well as helpful remedial measures.
Which tires are louder?

Air is then pressed through the tread grooves and sucked in again when the tread area loses contact again — a bit like an air pump that expels and sucks air. This creates noise.
Are all-season tires louder than summer tires?
All-weather tires are always significantly louder than summer or winter tires. Because they have coarse tread like winter tires but not as soft.
How does sawtooth make itself felt?
The tires that are subject to less drive or brake wear, for example the rear tires in front-wheel drive vehicles, are also primarily affected. The sawtooth wear is noticeable through reduced running smoothness and increased rolling noise.
Can car tires get louder?
As a result, older and worn tires tend to be louder than new tires. If the sawtooth gets worse, even driving behavior can be negatively influenced. This is noticeable, for example, when the steering wheel wobbles. In addition, the car slides more easily when braking.

In principle, it is possible to continue driving, but you should not simply ignore the problem. You can therefore continue to drive with a sawtooth tire and the sawtooth formation on the tire is not dangerous either. But you should act, especially when the sawtooth on the tire is already deep.
What is noisy engine or tires?
With quiet tires and appropriate driving style
The main source of noise in cars today is usually not the engine or exhaust, but the tires. From a speed of about 35 kilometers per hour, the tire noise is louder than the engine noise.
What are the disadvantages of all-season tires?
- longer braking distance than summer tires.
- higher noise level and wear (compared to summer and winter tires)
- worse handling in extreme weather conditions (snow and ice, extreme cold and heat)
- large temperature differences not ideal.
- Compromising on safety and comfort.
What speaks against all-season tires?
Higher wear: Since all-season tires have a profile similar to winter tires but have a softer rubber compound for summer, their wear is higher. You will therefore have to replace the tires with new ones sooner.
Is 71 dB loud?
Decibel (dB) is the unit of measurement for loudness. People perceive sounds between a sound level of 40 decibels and around 65 decibels as quiet, normal and pleasant. It gets loud for us from a volume of around 80 decibels. Scientists also refer to sounds above this threshold as «loud» or «noise».

Is 2 dB difference audible?
halving the volume is perceived. A sound level difference of 3 dB is considered perceptible, a difference of 1 dB is hardly audible.
How does sawtooth formation occur?
Sawtooth on the tire: possible causes
The sawtooth formation on the tire has a completely natural cause: when the rubber tread block is in contact with the road, it is compressed. If the tire continues to roll, it is relieved again. There is always a certain amount of slip.
