you should be fine on a 255/40/20 and a 295/35/20, with no spacers. They are an inch taller than the 255/35 and 295/30 I currently run, and are only off in diameter by a tenth of an inch, which is perfectly acceptable. they are only marginally, wider, and I have plenty of room and never, ever rub with my current set up.

Note that I use those sizes on M5 343M wheels, so the offsets are different.
