Probably need to see if a spacer has been used. Based on your comments, rear wheels don't have one. A spacer would allow you to still use the existing wheels, but would move the centerline out from the rear hub. The 285s are about as wide as can be used due to max diameter being the controlling issue to avoid any rubbing.
There are several online websites that will let you see the impact of a spacer. Here's a Link to the website I like to use:
CLICK. (Note: DUH! Just saw where you stated above that wheel spacers not allowed in your locale. RATS! You'd end up having to get a rear set of matching rims with a larger offset (would also need to see how wide a rim the 285s will mount on - See attached tire chart) to push the wheel centerline out from the present setup & use the same 285 tires.
Here's another that offers various options using wheels with offsets:

Lots of options to look at.
