The answer to that will depend on the trim of Your 2015 Dodge Challenger. Let's say You have either an SXT or R/T, the tire size will be P235/55R18, the recommended tire pressure for all wheels iS32 PSI, and the wheels are 18" in diameter with A7.5" width. If You'd like to double check and confirm that these are the correct numbers or if You have a different trim You can check the sticker that should be located along the door panel on the driver side of the vehicle. Keeping You tire pressure levels around 32 PSI is important for both vehicle safety as well as making sure You get a good balance of traction and fuel economy. -
