For SXT or R/T models, the tire size is P235/55R18 with a recommended tire pressure of 32 PSI for all wheels. The wheels are 18 inches in diameter and 7.5 inches wide. To confirm these details or if you have a different trim, you can find the information on a sticker located along the driver's side door panel. Maintaining tire pressure at around 32 PSI is crucial for vehicle safety, optimal traction, and fuel efficiency.
