the 285/35's are 26.9" tall & may cause your traction light to go on and off.
I personally like the tread width on the tire to be the same as the overall rim width;in your case,,,a 9.5 wheel is 10.5" wide & 10.5 wheel is 11.5" (that's Lip to Lip)
Michelin has a much larger selection with the PSS tire....but width's change with manufacturer-weren't sure if you were a fan of the stretched look or the fat/slight bulge or straight up & down.? something to think about.
Rear camber will play a huge roll in sticking out or not.
