What causes this "shredded" wear on the shoulder of both left tires (displayed is the front tire, 1 year old, ~20KKM)?
The wear on the thread area is regular, alignment was done, pressure is fine. The vehicle in question is a LHD Opel Astra H Caravan (no modifications). I drive mixed (1/2 highway, the rest is urban and mountain road).
The tires on the right side do not have this pattern.
