For the 2015 BMW X5 with the standard 18-inch wheels, the proper tire pressure is 35 psi in the rear and 32 psi in the front. The factory-fitted tires on the X5 are size 255/55R18. Maintaining correct tire pressure is crucial as it can prevent issues like uneven tread wear, which can decrease traction and fuel efficiency and even increase the risk of a blowout. Many people mistakenly believe the tire's max psi listed on the sidewall is the target pressure, but it's important to refer to the recommended psi indicated on the sticker in the glove box or driver's door jamb.

The responses provided earlier are not accurate. Please consult the manual. The air pressure required for the tires varies based on their size and speed rating. For instance, tires that are 18 inches with a 109H rating should be inflated to 33 psi in the front and 41 psi in the rear.
