I'm running 32 front, 28 rear on my Domane for the winter, both Bontrager AW 2s, although the wider Aoelus 3 rims might help with the fit. Over the summer, I did a fast century that had 20 miles of gravel, firm dirt, and washboard, with 25s on the same bike. Although it didn't bother me at the time, the bigger tires would have been better, particularly on the descents.
