All tires have a range of suitable wheel widths to be fitted to, and this is typically 1.5" from narrowest to widest. A few, like the 275/40-20, have a 2" range. This is per tire industry standards, not something that I am making up on the fly.
A 275/40-20 is measured on a 9.5" wide wheel - meaning that a wheel that's only 9" wide is almost certainly narrower than the optimum width for that tire size. 10" wide is an equal amount "off" the other way, and is the way to go if cornering, handling, and responsive steering are important to you. 275/40's are actually OK'ed all the way out to 11" wide rims, so 10's really won't make them all that "stretched".
What Chevrolet or any other mfr does after the tire is designed is a separate matter, and Chevy's fitment to 9" wide wheels likely involves making the ride a little softer and the handling just a little less crisp for people who can't hold their cars in a straight line very well. That's Chevy's compromise, which doesn't have to be yours.
It's the actual you-have-to-drive-it difference in feel that might convince you, not what anybody posts on an internet message board.
