next question is when to pump.
pump less on a cool night?
pump more on the hottest afternoon u can find?
and of course, a short drive from start when the tyres are still
not that warm yet..
Sinicker is right. Whenever I pump 230kpa in the afternoon, the
next morning when I check, will be about 217kpa.
Similarly whenver I pump 220kpa at night or very early morning,
when I pump in the afternoon the meter will read 235kpa.
Not that I have a fetish for pumping air, but I inflate the
tyres about once a week as a habit and I always do the
twice-approach as above, ie (night pump + next afternoon check /
afternoon pump + early next morning check) - so as to be sure I
don't have a slow puncture as I've a bad experience involving slow
punctures. From outside may look ok, but there was once I was
running all day long on a slow punctured tyre which had only 54kpa
at the end of the day before I realised - I totally ruined the tyre
+ sidewall. Very lucky never explode.
