Ever wondered what makes wet tyres different from regular ones? Designed for motorsport, wet tyres feature unique tread patterns that channel water away for improved grip on rain-soaked tracks. Here’s how they work, why F1 drivers use them selectively, and what everyday drivers can learn about handling wet conditions safely.
If there’s one weather condition we need to be prepared for in the UK, it’s rain.
However, it’s not wet tyres that regular drivers get when it starts to rain. Instead, winter tyres are the norm for those upgrading and preparing their car for adverse weather conditions.
So, what exactly are wet tyres and who uses them?
What Are Wet Tyres?
Wet tyres are a type of high performance motorsport tyre, used when race drivers are racing on a wet track.
They replace the slick tyres that are used in dry conditions and are uniquely designed to ensure that the driver remains safe on the road with optimum control, excellent handling, and high performance.
How Do Wet Tyres Differ From Slick Tyres?
Wet tyres have been designed with more grooves between the tyre tread blocks, in an effort to displace surface water and optimise the driver handling on both straights and around bends / on sharp corners.
However, this has created some issues among F1 drivers – something that Pirelli, as the official tyre supplier for F1, is working to fix for the upcoming 2026 season.
At present, it is found that the smaller tread blocks, constructed as a result of the more complex grooves design, overheat when driving on wet road surfaces. This leads to a loss of grip on sharp corners, which impacts overall driving stability.
What Can Be Done to Improve Wet Tyres?
For wet tyres to offer a better and more consistent grip, both the compound and tread pattern need to change.
At present, the smaller tread blocks mean that they move more with the vehicle – however, they need to move less to lower the amount of heat generated between rubber and surface.
Pirelli is investing heavily in rainy day testing and is prioritising both new tyre compositions and designs to get a handle on what works best when it is raining and when there are high levels of surface water.
