Avoidance of pinch flats is an excellent reason to go to 28's.
28 mm tires: Get them for the pinch flat avoidance; stay for the ride comfort.
Pinch flat resistance is one of the main reasons for going tubeless. The other significant reason is the fact that there is no tube to heat up on a long down hill run and cause a blow out.
In the past 15,000+ miles of tandem riding we have NOT had a pinch flat, front or rear. 23mm or 25mm tube or tubeless therefore for now I will stay with the 23/25 setup. The 23 on the front is supposed to provide a slight aero advantage. We are happy with the ride comfort!
