It sounds to me like you aren't actually getting air into the tyres at all, just the line. Make sure the valves aren't sticking and if they are presta give them a push to start them off before you put the pump head on. If they are Schrader, make sure you are using the right part of the headBought a new track pump from halfords, own brand one for £20. Checked my tyre pressures and i can't get my tyres above 65psi although the tyres state 85psi? The pumps definately working as i deflated and inflated but as soon as i hit 65psi it just didn't want to budge? Any ideas?
Well, whatever the problem was its now sorted. Got home today and had another go and hey presta, 85psi no problem!
Postscript: there are two possible problems: firstly the little stalk in your valve may be sticking shut - it helps to depress it briefly before you connect the pump so as to free it. Secondly and more likely is that you bought a pump with a fat barrel for MTB tyres and you simply can't achieve the pressure. A track pump for road bikes needs a long thin barrel to enable you to get the pressure, not a fat short barrel. My walking buddy bought a cheap pump and it's fatter than mine so you need muscles like a gorilla.
