Problem Inflating tyre's

2014 nuevo with alloy wheels .has anyone had a problem inflating tyres I have foot pumps and 12 v pumps but the connection will not allow air into the tyres ,I have screw on and clamp connectors . the only way I can inflate them is with a 240 v compressor and a push and hold professional connector . is it because of the bolt on valves ? ..anyone had the same problem

I purchased a couple of tyre valve extenders from Halfords , the valve extenders screw onto the existing valve allowing you to attach a foot pump or 12 volt connection.
Unscrew the extension valve and remove to a safe place  as it will fly off when traveling.
