You should change all the tyres to be the same size. once changed rotate them around the car every few thousand miles and this will wear them out all about the same. putting different sized tyres on front and rear will cause allsort of odd handling characteristics and if you locked the centre diff you will have 2 wheels turning at a different rate to the other 2

You don't say what aspect ratio you'd be fitting - 205R16's are 80% (if memory serves, so really 205/80R16) so your 255's would need to be 255/65R16 to be even close to the same diameter. To calculate old Vs new size, have a look 1/3 the way down this page for a calculator.

Even then, assuming you can match the height, odd widths will look strange. Plus, in matching the height of the 205's, you're missing out on the chance to fit taller tyres and increase ground clearance.

I'd bit the bullet and upgrade the whole set rather than having odd tyres.
