A pair of schwalbe lugano 700 x 23c wire bead tyres, fitted on saturday. The rear one blew off the rim (massive bang!) when it had just been fitted (i was in the shed when it went-loud!) suspecting my poor fitting technique, i replaced the tube and went riding.
After half a mile, both tyres had started to unseat from the rim, with the tube starting to appear. I quickly let the tyres down and went home to check and reinflate. I did this but it happened again on the ride. I have since borrowed a pair of tyres which have been spot on. Should i send the tyres back (they only have 10 miles on them!)Tried at 6 and 7 bar (recommended min, 6 and max 7.5)
Is this a Schwalbe thing?
