Having recently bought a new Quinny Formula, I decided that the tyres could do with a bit more air. As dh is a bike fanatic and as the handbook for the buggy said that the tyres on the Quinny work the same as those of a bike, I got him to sort it out. The problem is, as soon as you start detatching the pump from the valve, the air rushes out and the tyre is flat! I have less air in them now than before!! Has anyone else had a similar problem? Someone said yesterday that I should get a footpump as you can release it quicker thus preventing too much air escaping. Thing is, I don't really want to fork out any more money being that I've spent a small fortune on this buggy and the pump that came with it. Any ideas what I'm doing wrong? Help!
