40 F/ 38 R for now. I may up that a lb. or 2 if the weather ever warms up

in what conditions?
I'm sure a drag racer is gonna run different than a daily driver who would run different from an autoX, etc.

 

[MooseX]

just day to day driving on stock tires. but if anyone is using them for Auto X or track I'd like to know that too

 

[fastrack]

ran auto X and first run was at 43r 42f. Cold day (50's), best results were at 41r & 40f. The rear of the car was much stickier with less pressure.

I checked yesterday to found my car had 50 psi in all 4 wheels wtf? I took the air out to 38 psi and i got SERVICE ENGINE SOON light. Does anyone have some comment about that?

[civicsi_X]

Because your PDI was probably performed by a high school kid right out of Lincoln Tech or UTI.

You'd probably want to up them when the weather cools down, rather than warms up, because the added heat will increase the pressure on gas.

I'm actually going to lower it to 38 F/ 36 R real soon. Anyone else know what pressures they have going?

 

[Robevo]

Actually the tire pressure is depend on your tire type - size,and the race you running. Plus the weather condition.
I didn't race the X yet so i have no clue. On stock tires i wouldn't go over 36 -34 or 36-32 on road course, for start.
Of course this is personal reference too.
