    After getting home with my new HC, I thoroughly went thru it and found it to still be set at transport inflation tire pressures (51 psi all around) which is necessary to protect tires during transport and on dealer lot. However, for regular driving they should be set to what is posted on your door label for tire pressure.- on my Challengr HC that is 32 psi. I set mine to 33, as I'm still not "using" the car hard during break in period. The idea being that when the tires get warm and psi increases you want a nice flat contact patch on the ground. When I start hitting it harder the psi will be lowered to 32 for street driving (lower for performance driving that will heat tires more). So double check the tire pressures.

    Note that high pressures will make an HC quite twitchy, especially when cornering since the tread will be pushing to the road in the center rather than evenly. Hope I'm not being to "basic" with this, just want all the new HC owners to not have surprises and experience all an HC can really offer.

    you can check the tire pressure in the information window on the dashboard, right?

    That is correct - under Vehicle Info > Tire pressures. I find the readings to be quite accurate. Note that you need to drive a little to get tires rotating to get the most accurate reading.

    I was just about to search for this. Thanks for the post. I noticed yesterday (a week after taking my cat home) that the pressures were 49-50 psi all around. Lowered to 32-33 psi. Maybe I'm crazy but I can feel a difference even in regular driving. I'm going to drop a line to my sales guy at the dealer. I can see them selling a 200/300 without checking tire pressures, but a Hellcat?

    Guys, the reason that the truck driver increases the tire pressure to the upper 40's & lower 50's is so that the front splitter doesn't scrape while unloading the cars from the delivery trailer so everyone should be checking and adjusting their tire pressure right after they bring home their cats. Good point Doug_38 because not many on here think to double check their tire pressure when they get their cars initially.

    lol i heard the reason its set so high is so the tires dont flatspot sitting in one spot so long after build prior to delivery.

    in any case, its normal. Lower the pressure to 32

    That actually sounds more believable. I mean how much higher is a tire inflated at 50 compared to 32 anyone know?

    Absolutely agree 100%. Tp should be done on pdi. And we need to check it to make sure the tires don't wear wrong. Warranty issues are documented in tires for no coverage. So it makes sense what you did. Kuddos brother

    Great point, thanks for the reminder. I know mine are between 45 and 50 right now. I never thought to check them.
