i always pump according to the spec but that figure can only be used when its cold and the pump station 1km or less than the first time the car start moving...

if u already drive the car in a hot day noon/afternoon...always pump up 20-30kpa higher...

let say the figure at the driver door stated 200kpa...then at afternoon please pump 220kpa or 230kpa as the pressure will become lower at night when cold and become +-200kpa...

if u pump 200 in a hot day noon...at night it will become +-170 and the tire be underpressure

If manufacturer recommends 32front/30back, make sense to put front/back to 32psi?
Both front/back tyres same size

if at the driver door didnt stated to pump up more if car is full load then it isnt necessary...

my car stated that i have to...if normal usage 4 people and few luggage need to pump 210kpa when cold front and back...if 5 people and full luggage in bonnet have to pump when cold 230kpa front...290kpa in rear...

my other car stated drive below 160kph pump 210 front and rear...if intend to drive more than 160kph need to pump 230 front and 260 rear...

so...in my opinion...follow the pressure recommended by the manufacturer...lil bit more still ok...and always pump up 20-30kpa more in the afternoon after u have drive ur car for a while as the pressure will become lower at night when the tire cold
