Every year tyre manufacturers combine the latest design and manufacturing creating so tyres of unparalleled quality.

Let’s begin considering how tread compounds are really important, obviously they are different from the rally cars’ compounds, but have some features in common: drafting, for instance.

In order to draw a comparison, Formula 1 tyres are designed to have a durability of 100-150 kilometers, therefore they undergo acceleration, rubbing and abrasions that an average tyre could never bear. Considering that a F1 does 0-200 approximately in four seconds, a sport car, on the other hand, reach that timing in 0-100. Coming back to the core discourse, a daily used cars’ tread compounds have to ensure gripping capabilities which are suitable for all weather conditions.

What is a compound introduced in 2021 like? During the tumble, the tyre grips on the asphalt giving more traction, when it is not capable of holding the grip, a slippage is created, losing this way traction. More the asphalt is warm, more the compound warms up giving more ‘’grasp’’, but a better clasp on the streets supply, indisputably, great performance obtaining so the maximum tightness but it is also necessary to consider its remarkable increase on tyre and fuel consumption. Accordingly, even if manufactured tyres provide a consistency of 45.000 kilometers, it is always recommended to run a tread control in order to assure that it is in its minimum value, otherwise it becomes dangerous to continue with your daily rides.

Talking about tread, the design that we can see around our vehicle’s tyre, they have a purely engineering purpose rather than an aesthetic one. The spaces that we can see between the tassels can be separated into canals and they are used to convey the water out of the tyre. According to the law, all the type-tested tyres have to grant minimum values of gripping in case of dry, wet or flooded asphalt.

A tread could work for all seasons?

Potentially yes, but not effectively. It all depends on where one drives. In Northern Italy, for example, it is very common that it snows, so it is mandatory to have winter tyres from the 15th of November to the 15th of April because the streets get more dangerous due to the snow and ice. A winter tyre has compounds which permit of properly working even in below-zero temperatures, while a summer tyre struggles to adhere to the streets when the temperatures are too low and the snow can trap in between the tread canals reducing a lot holding capacities.

There is also a category named ‘’all seasons tyres’’. These tyres have the advantage of hybrid quality and are designed to be used whole year around, but it is important to consider that they won’t have the same gripping of a winter tyre on a snowy/icy street and they won’t even have the same holdness of a summer tyre.
