I have a 2000 S430 with AMG Monoblock 19 in 8.5 inch width in front and 9.5 in in the back. Anyone know the maximum width tires I can get?

285/35 rear 255/40 front??
285/30 rear 255/35 front??
275/35 rear 245/40 front?

I want to go maximum width. Do I want to avoid too low a profile for damage?

I'm getting conflicting reports from people.
