Naughty Boy

You inflated two tyres ok. 
 
You mucked about with the third. 
 
You let the air out of the fourth!!!
 
Your replacement is on order!!!!
 
 
Fortunately I have the portable electric tyre inflator in the boot.  It struggles to reach the 39psi for the tyres, but it does finally get there.  Hopefully the new hose will arrive by the time the tyres need inflating again.
