Having upgraded from 36"(original) to 40"(non-folding) wheel in 2001 Bavaria 40, I find it much easier to steer on side bench while close-hauled in choppy conditions.
The locker lids bend slightly when opening and touching the wheel, other than that 40-in wheel fits perfectly. My solution in carrying goods is to remove the wheel intermittently - the keyed taper retaining nut is easily undone by winch handle.
