ADAC (Allgemeiner Deutscher Automobil-Club e.V.), Europes largest motoring club have published their 2009 winter tyre test.
As always, ADAC have been extremely thorough testing 34 different tyres across two tire sizes. All the tyres were purchased anonymously from independent retailers to avoid any "special" test samples being delivered by the manufacturers.
The winter tyres were tested on dry and wet roads, a specially created snow surface and the local ice ring to emulate icy conditions! The characteristics taken into account were
Subjective dry handling during every day driving
Subjective handling during emergency situations
Straight line aquaplaning resistance
Cornering aquaplaning resistance
Snow traction and stability
The results are broken down into 5 groups from highly rated to not recommended.
