whats up all, in my manual it says to check tire pressure when tires are cold,but how much will the pressure fluctuate when the tires are warmed up.(by the time i get to a gas station to adjust the pressure)how much (over) should i take into account when i check them hot? .....i have a 98 impreza rs with minor mods, should i run the suggested amount , 32 f 29 r ,or higher/lower the pressure? i pretty much only drive semi hard in the backroads, rest of the time i mellow out. thanks in advance !

 

i noticed probably about 1-2 psi difference. my cold pressures are 32/29 front/rear, and I inflate to 34/31 when they're warm.

I tried inflating to 32/29 warm, and when i did check the pressures after cooling down, they read about 30/27-28...

 

hey, thanks for the info, now ill start messing with psi for push and understeer conditions.... later
