not sure about KPA; but normally i pump around 32psi.
from the pic; tat should be around 221kpa
a normal 195/50;55 series max is up 50PSI only.
but no body is crzy enough to put so much
when u pump 32psi into a cold tire; when it gets warm up u should be getting around 35-36psi or even higher
Regarding this cold tire and warm tire theory I read on BridgeStone website too. But I just don't get what cold and warm meant to the tire. I am driving to the petrol station to pump my tires which means they are warm , I pump more kPa right ? But in normal tires shop they pump the tires as if they are cold right ? Then how much is the exactly kPa shud add in a warm tire compared to cold ? Could it be calculated ? Does the pressure of tires affected by weight of car too ? Heavier front pump more ?from the pic; tat should be around 221kpa
