You dont have any problems with the tire fitting the rim, I have a 2004 Mach 1, I didnt think that a 285 would fit on a 17x9 wheel.

I seriously don't think 10mm wider will be harmful in any way.

Otherwise, it's about the same size, only .3" taller than the 275.
275mm x .40(%) = 110mm
285mm x .40(%) = 114mm

So, that is only 8mm taller total (counting 2 4mm sides).
