Hello dear Yaris community, have tried the search to find nothing to my question. the following phenomenon: Our friendly Toyota dealer gave us around 20mm per wheel bolted track widths. In winter our little one ran on 175/65 R 14 (taken over from previous Corolla) with track plates wonderfully straight. Since then the change back to the series TS-summer-alus makes the steering what she wants: 1. Track fidelity against zero, constantly you have to correct. 2. to the left “falls” the TS into the Turns, to the right you have to press more strongly on the steering wheel. Info: mileage: approx. 8.000km, of which approx. 50% on summer tires, normal driving mode. Last year was measured vehicle, all values in the standard range. thank you for your help, gruss TouranJojo
