Much has been reported about winter tyres and how they can prevent accidents and save lives, but now Autocar have carried out a major investigation into how they perform in the wet during warmer weather.
According to Autocar: “Winter tyres offer greater cornering performance than summer rubber in everyday wet weather conditions – but they do take longer to stop from 70mph. These are the major findings of an Autocar investigation into how winter tyres perform in warmer weather.
“It’s widely known that winter tyres provide better performance in temperatures below seven degrees celsius, but how they’re performance is affected in warmer weather is less clear.
“Autocar took a set of common, everyday premium tyres and compared them to a set of winter tyres, testing braking and cornering performance in wet conditions at 10C.”
Using a Ford Focus as their test vehicle, they found that the Michelin Alpin winter tyres provided substantially better lateral grip and general feel over the Michelin Primacy HP tyres.
However, the winter tyres took 7.1metres longer to stop from 70mph in these conditions than the everyday tyres.
Steve Dolby, Michelin’s product marketing manager, told Autocar that this would be due to the “specialist tread and compound in the winter tyres resulting in more flexibility in the tread blocks when under higher forces in warmer temperatures.”
He also explained that “clearly the tread in the winter tyres was successfully evacuating more water than the Primacy tyres on the wet laps, but with heavy braking in warmer temperatures, the more stable tread pattern on the everyday tyres helped provide better braking.”
