In its recent test of ten summer tyres in the performance size 245/40 R19 98Y, Auto Bild reports that an original equipment tyre tested “by chance” alongside the aftermarket models delivered an “alarming result” in the wet braking test. Elaborating on this strongly worded evaluation, the motoring magazine explains that the OE specification tyre had been tweaked for optimally low rolling resistance – and thus minimal fuel consumption and CO2 emissions – at the expense of stopping distance on wet roads.
