Mixing front and rear tire widths

[ls0725]

i have 2 road bikes, one has 700c x 28 tires, the other 700c x 23. i tried to experiment once to put the 23 (thinner) in front and the 28 (thicker) in the rear. it had a good ride actually, in terms of balance, ride, grip, etc.
is this a no-no or can i get away with it? what are the consequences/advantages? Thanks.

I don't see any reason why you can't mix.<br />
Time trial bikes used have different diameter wheels as well.<br />
MTB bikes sometimes have different sizes.<br />
Advantage maybe more comfort with the bigger tire on the back, due to more weight on the rear.

yes comfort was huge with the thicker tire at the rear. i imagine there wont be a problem since the overall diameter of the 2 tires are the same.
