...laut Amis sollen 235/40 17-er die Maxgrösse ohne Kotflügel bördeln sein. Mit bördeln sollen auch 245/40 17-er gehen
. Die Frage ist dann ob es bei uns erlaubt ist.
Auszug aus Abschnitt Max Tire Size: Quelle Good-Win-Racing
Maximum tire size that will fit in stock fenders without a fender roll is 235/40/17 using our Advanti Racing, Konig HyperGram, and 6UL Racing Wheels in either 17x8 or 17x9, as long as you have about 1.5 degrees of negative camber or more. If the car is lowered and/or raced, this size will typically rub the plastic fender liners inside the wheel well at full steering lock and/or over big bumps/dips in turns depending on amount of lowering and amount of lowering and amount of negative camber (same story with taller 225/45/17). This is all even more true for 245/40/17, which can be used by SCCA STR competitors with a fender roll. Picture above is our own Fiat 124 with our 17x8 Bronze 6UL wheels and 245/40 tires, and lowered with KONI SPORT shocks and our Race Spec Springs.
