Which tire width? (28mm vs 30mm)

Going 28 front and 30 rear is an excellent idea. I don’t expect to be in any sort of a pack where I couldn’t maneuver around holes during the vast majority of my rides. I’ll probably switch out the rear on my current wheels for a 30 as well.

Hasn’t the strict 105% rule been debunked? I recall one of the key proponents saying that it is no longer that simple. Instead, ask the wheel manufacturer what the most aero width is for their particular wheel. Which makes life more complicated.

Sorry that is vague, I can’t remember the specific references.
