If they are only a 9'', I would stay with the 275's then. The sidewall would stay the same, 40, but I would still keep the 275's cuz 285 might buldge if they are wide. Goodyear and BFgoodrich tires seem to be a bit on the wider side, so go with one of those in a 275 if you dont already have um. Otherwise, get a wider rim in the back if you want to be safe and go wider. You will lose sidewall stiffness with the wider tire on the smaller wheel and therefore, lose some cornering ability if that matters to you. Some people do run a 285 on a 9'', but that is a choice and not a recomendation.
