A puncture is A Puncture , no matter what the Brand ..

I recently bought Schwalbe AV 4 Tubes for My Brompton since 349 35 Schrader tubes are hard to find . [AV= Auto Valve ie Schrader]

they are a skinnier tube , so tire fitting is a bit easier , But as they must expand to fill a larger Volume,
the actual tube is expanded, Like Balloons, to be thinner wall ..

Schwalbe does include a ring nut* on the threaded Schrader stem, so pumping them up with a Press on hose head is easier,

*same with the Dunlop/Woods Valve stems, also bigger than the Presta Stems. .
