26" won't run well, so we will not use 26" for sure. and our bike is made for 28", and it's absolutely great. We're now using a Specialized Pathfinder TLR Gravel Racing 700x40 instead of the Gravel Grinder 700x34, pressure is 3.4 bar, so not too much, but sufficient, the problem seems to be solved.
The strange thing about it is: We tried what
tandemdr suggested. Front weight 75 kg, back weight 65 kg, not including luggage. That's a total of just 140 kg. We carry luggage on the back rack, so we have to add a 15 kg for a longer trip. This would be almost the same weight for both wheels. Why do we get these snake bites on the back side only? No matter, we did some hundred kms without any problems, so it seems to be OK now.
