pic rel is a 28mm, and peloton is now running 25mm as a standard, as oposed to 2000s trend of 23mm, and in the 90s it was 19mm and 20mm tires.

In many of the gimmick new trends in road bikes (im looking at you 10-12 speed casettes and discs), going bigger tires is a positive move. Personally I run 20mm on a road bike, and 30mm on my commute and the difference is offcourse huge (20mm sucks btw but im stuck with them for now).

Tires on road will probably go to 28mm as a standard soon. Question is will the standard tires in the peloton go to 30mm? 32 seem to be the point when the profile of the tire becomes to tall which makes it flexy in the corners and less responsive (with 30mm tires, bike still feels like a very responsive road bike imho).

how wide is too wide? I say 32 is too wide for a road bike or the upper margin at least.
