I'm running 20x10" 25mm 285/35r20 and 20x11.5" 18mm 325/30r20 with no problems apart from a tiny bit of rubbing on the front wheel linings when on weird angles going up driveways or similar. When I ran 20x10" 34mm at the front with 295/30r20 I didn't have that problem so I think the issue is the height of the tyre.
