996 Wheel dilemma

[derbylad]

Do 10" rear wheels with 285 tyres fit on 98 996?

Basically I want to put Sport Design (GT3 look) wheels onto my '98 996.

Not sure where I'm going to get them from yet either Used parts dealer or Ebay/private seller. But I want to make sure they fit before I buy some then find out they I can't return them.
I'm just checking because the Tyre pressure information under the bonnet does not mention 285 tyres just 255 & 265.
