For better ride, handling and brake cooling the QX50 has standard 19-inch wheels. Smaller 18-inch wheels are standard on the GLC.

The QX50 has a standard easy tire fill system. When inflating the tires, the vehicle’s integrated tire pressure sensors keep track of the pressure as the tires fill and tell the driver when the tires are inflated to the proper pressure. The GLC doesn’t offer vehicle monitored tire inflation.
