Interesting, thanks.

My 25s are definitely a fraction of a mm narrower (I can touch calipers to the 24.2mm rim and the rubber is not touching at most places on the circumference), but that's at about 90-95 PSI.

Reckon there could be any issues with running 23mm up front and 25 at the rear with the slightly different heights affecting the geometry of the bike?

I can't sense any problem with that but I have it right from the beginning of this one so I have nothing to compare.

finished a crit safely today with the bike tho so I guess there shouldn't be any issue.... hopefully.

@jlok. Thank you for the measurements. I forgot to ask, are those measurements for the clincher or tubular version of the Vittoria Corsa G+?

It's all downhill from here, except for the uphills.

I only use 23mm (or 24mm if you count the Spec. Turbo Cottons) tyres on my 17C boras (24.2 external) and all inflate to between 24-25mm which is perfect to me. 25mm tyres (only tried GP4000 S2) baloon to >27mm which looks awful and (i suspect) would not be very aerodynamic either.
