I bought my 06 KJ used, and it came with a set of Coursers on it. My TPM says that they are all inflated in the low 40s PSI. Out of curiosity I checked the drivers door sticker and it suggests inflation of 33 PSI. I know the higher pressure will get me better gas mileage. Is there any reason I should get them down to 33? I guess there could be a traction improvement this winter, but is there anything else?
