before fitting the rim tape go right the way round the rim 2-3 times with electrical tape. go over the valve hole. before fitting the tube stab the valve hole open with a screwdriver, but dont trim the excess
this "tapes" the edges of the valve hole
The rim tape i've used is pretty thick, about 1.5mm and surrounds the valve hole perfectly.
The punctures are appearing ~1cm to the left of the valve hole, dispite there being nothing there to cause problems.
I'm actually baffled by this because there doesn't seem to be an clear indicator as to what is causing it.

Yes I do put dust caps on but they're made with helium nano technology so they actually reduce the weight of the bike
