Meal! As it should be for a new vehicle, I “marked” a summer rim (BMW – around 400,- EUR) after 2 months, in which I have in parallel a high kerb of gaaaananz easily touch 1.) Why has the rim guard not “protected”? (255/45 on 9×18) 2.) With self-grinding and brushing over it is not done here, what does the professional (and at what price) do? Merci
