Volvo V70 II rear axle tires worn irregularly

Moin, I noticed increased wear on the rear wheels during the rudder change, the tires were completely worn out outside. Generally the result of wrongly adjusted track or fall, however, the car was only in the summer with the axle measurement. The tyres are now on the third season, about 60,000km. Last summer this was no problem at all, because the tires looked great when changing. Now my question: does the error picture indicate a certain problem (damper/spring etc.)? Thank you!
