Maximum width on the front axle, what is possible ?

Moin, very short question. What did you have on the front axle for wide rims? And which tire sizes ? Please no answers with 8,5J. Please only those that go beyond standard. Important is only the front axle. On the rear axle I already know the maximum. Of course without having to work. All original. Background is that the combination with my chassis and 20 inches I don’t like completely. However, since I am an absolute optic fanatic, I wanted to be wide at the front here rim with a nice rubber ride. Either I remodel my 3 parts 19 inches, or I buy something else. Very special would be intressant if I got a 10×19 inch rim with a 275/30 he tires under front? That would be fantastic, then I could really drive a really horny rim. then would be like now 11x 19 to mount with 295 he matures, that fits without problems by the way:Who has interest in 20 inches rims of my sl? Are really chic. But I think there The rubber is a little too thin for my driving profile.
