I was just curious.
+40 is not even "sort of close" to +22. Depending on all the rest of the important stuff that goes into making wheels "fit", that 18mm difference can be the difference between everything clearing by half an inch and hard interference between the wheel or tire and some hard chassis point such as the strut, the front sta-bar, or the tierod ends.
That's if the spokes even clear the outer faces of your calipers.
"Very close" to +22 would be something more like +24, and there will be situations where even that won't be nearly close enough. Trust me on this - I have fit wheels without using spacers to less than 1 mm clearance to outer tierods before.
