Wheel box inner cover damaged by tires

With my XC60 MJ 2010 D5 the inner wheel box cover is really eaten out by the tire. First I mean that someone on the right side cut me the interior cover with a cuter knife. I really don’t know what that is (have enough distances from the tire to the inner lining) Have already hit to the right and left fully but nothing. please for help with what this is related to. Ps : I had only when I mounted the winter tires (the glued like last year 235/65/17) No snow chains no terrain No Teirbisse
