Presta valves my friend. Another new pump purchased and will see how that works or doesn't. Got the Mini Morph as suggested by one of the contributors.Not sure what type of tyre the OP wants to inflate.
As a bike shop mechanic said to me, the fatter the tyre, the fatter the pump you need to inflate it.
I found this out the hard way recently when my Blackburn Air Stick wouldn't put more than about 20psi in 20" balloon tyres.
