Tire wear XC90 uneven?

On the inside of the tires there are still a minimum of 8mm profile on the Laengsrille after 29tkm, while the outer laengsrille has only 2-3mm. And this on all four wheels. Have you observed similar things? This is not normal, but it won’t be a adjusted track/sturch either, since it affects both axles the same way.
