Hello! A question for experts in the area of chassis geometry: I want my Exeo ST (= like Audi A4 B7 Avant) to drive as straight as possible on the motorway. Drive moderate speed (120 – 140 km/h), no racing ambitions. Is it true that smaller tyres (allowed are 205/55 R16 to 7×16 ET45) will keep track better than the likewise permitted 225/45 R17 to 7.5×17 ET42 or 245/45 R18 to 8×18 ET42? And is it really true that narrow tires track grooves are less strongly reduced Thank you very much for your expert input.
