Nick, I am measuring them from cold.  
 Here's the procedure.
 Get bike out of garage.
 Check tyre pressure (yes I have a digital tyre pressure gauge of my very own).
 It's invariably 4 - 5 lbs down on the front and between 2 and 4 on the back.
 Take it to garage (200 yards up the road)
 Add air. 
 re-measure pressure next time I get bike out - about 5 - 7 days later.
 pressure dropped again. 
 I have to say, I think it's something to do with the fact that I'm riding on these 208RRs.   I've never had this drop in pressure on any tyre before, unless I actually had a slow puncture.   
 And what about the tread???  Where's you're reply on that? 
 Leave it till you're sober to answer because I don't want to have to struggle with some uninteligible drivel - (she can bl00dy talk! 

)
