Tire pressure

[GS163]

What tire pressure should I be running with the SRT wheels and the F1 tires. I seem to be getting conflicting answers in the search that Im doing. TIA.

factory SRT spec is 32 front and rear.

I run 34 front and 32 rear.

I run 30psi in our 300C it rides good and handles well. But dont 4get that on long hauls the tire PSI rises because the air in heated and expands My tires got up 2 45psi from Miami 2 Atlanta doing 90mph.

On my Caddy you could scroll through the dash and read the air pressure in each tire. Does the 300 have that feature or only an idiot light when it reaches a certain point?

If your 300 has the TPM's (Tire Pressure Monitors) then you can scroll through your EVIC and check the tire pressure. The only way to get the TPM's to make a Bing noise and light up on the EVIC. Is when the pressure in the tire is lower than the parameters that the TPM is set for. Also if you get aftermarket wheels and the TPM do not fit in the wheel or you go to the track and let out some air below the parameter. Every 10 minutes the car goes bing, and flasshes flat bar readings on the EVIC screen. Then goes away until 10 more minutes and so on.
