Tyres striped

Hello TT ́S just came from the MFK (Tüv main examination) and see there – nothing is; completely failed!!! So here is the problem: TTQR 225ps rear 20mm distance and 40mm lower; front only 40mm lower; serial rim 17″ with the 225 rubbers And now the Mr. “Oberprüfer” seems completely not pleased. After the test ride with about 100 things over the paragraph (rain channel in the test area) pulled and simply said so: now they just have to get rid of the strip. was my answer: Question: where could the tire really be striped; I have not noticed anything yet – but statement by Mr. OberAr… : in a fully loaded condition can there not be striped nothing!!! My guess is through the new tires that wanders somewhere on the wheelhouse cladding made of plastic? Other ideas??? Thank you already for the numerous tip`s Norbi
