Fitting Vittoria EVO 55g Tubes

Hi all,

Has anyone fitted these tubes before?
I found them to be extremely tight and they barely fit over the rim. Can't get the tube into the tyre and will most likely pinch against the rim and tyre when you pump them up.

Have not experienced this with other lightweight tubes, they fit easily into the tyre itself.
Guess why these Vittoria's are so light, there is way less material!
