I recently fitted a set of 17" 'star' audi alloys to my A4, I went the other day and got a brand new set of Kumho tyres fitted. However ever since I did that, when I turn left around a corner that is not level I get this scraping sound from the right rear wheel. Anybody any idea what this is? I was thinking maybe its related to the car being up on a lift and has disturbed something? I dont know. Any help would be muchly appreciated. Tom.
