Deep rims? If so then not too wide otherwise you lose a lot of the aero benefit.
Shallow rims, go as wide as your frame will allow and enjoy the comfort!
40mm deep. I don't believe in aero gainz on bikes, because I'm a very non-aerodynamic human shaped object
Well I think you've answered your own question then, go as wide as the frame will allow. Honestly, bikes don't look much different with 28's or 32's.
