Eh, this is another area where construction is a factor. Flats due to low psi are usually pinch flats, which is a clincher issue. If you can bear the expense and inconvenience of running tubulars, pinch flats are no longer a concern.
I guess you could try tubeless as an alternative to tubulars too. They also tend to offer lower rolling resistance than tubs.[1]
I’ve got tubs on my TT bike but for general summer riding I like latex tubes in clinchers. Latex seems to be more resistant to pinch flats as long you take care fitting them. Spare tubes are butyl but not had to fix a latex puncture in the last 2 years.
(Winter and commute bikes are butyl for convenience)
...but tubular tyres at too low a pressure tend to separate from the rim in interesting ways - hope you brought tape or glue to stick them back in place.
