All-season tyres have found favour with tyre testers in recent years, but Auto Bild points out that most tests focus on tyres for small and compact cars. To address a dearth of testing for sporty mid-sized saloons, the German motoring publication has evaluated 32 tyre models in size 225/50 R17. In Auto Bild tradition, the testers performed wet and dry braking tests to pare down the field of candidates to a shortlist of the 16 top performers. They then subjected the finalists to various tests in dry, wet and snowy conditions and also evaluated characteristics such as rolling resistance, mileage potential and price-performance ratio.
