Need 300 SRT Design or SRT8 Tire Pressure Settings

**albertojedi** · 09-22-2009, 04:04 PM

Recentrly bought a 2006 Chrysler 300C HEMI modified with the SRT Design 20" rim. Car originally came with 18" wheels, hence the tire pressure should be approx. 30psi. I suppose 20" tires with the SRT Design 20" rim should have different pressure settings, but I don't know which are and have not been able to find them on the internet. I want to use as reference the SRT Design or SRT8 pressure settings. Can anybody help me on this?

same 40psi per tire. Even my new Invos are sitting at 38-40PSI per tire.

I prefer 35psi.

Excellent, thanks. Why do you prefer 35psi? Less bumpy? Are these pressures the ones recommended by Chrysler?

Alberto,
Vaya con las 35 libras, el 40 es demasiado alto y causar un desgaste desigual y no como un buen paseo. Disfrute de su 300.

Actually I think 32 is what Chrysler recommends. I shoot for 35 cold, but driving around they go up to 38 or so.

Thanks to everybody. So it seems that pressure ratings are almost the same both for wheels mounted on 20" inches rims (32 to 35 psi) as for wheels mounted on 18" rims (30 psi).
