Model X, 40,000 km. There's a consistent humming noise from the rear wheels while driving, most noticeable at speeds of 35-40 km/h. You can feel a slight vibration in the floor when sitting in the back seat. I've been to the dealership a couple of times for this, and the last time, the technician confirmed the noise. After checking, they said the half axles are fine and concluded it's due to tire aging. I've heard that 21-inch tires tend to wear unevenly and might need replacement around 40,000 km. The tires only have 40,000 km on them, and the tread still looks clear. Is this really possible?

How many kilometers do you guys usually change your brake pads? Yesterday, during maintenance, the technician said the brake pads need to be replaced, but I've only driven 40,000 kilometers. Shouldn't need to change them yet, right?

Hi everyone, I want to ask about the 2024 Cayenne. When I bought the car, there were no 21-inch wheels available, so I got the original 20-inch ones. Now I'm planning to change them. Should I go for the 20-inch bird's nest wheels or directly switch to 21-inch tires and wheels? I'm not very familiar with this. I've heard that 21-inch wheels might affect comfort and increase noise. A friend who repairs cars also says I don't need 21-inch wheels, but I'm worried I might regret sticking with 20-inch. Any advice?

Hey everyone, at how many kilometers should the timing belt be replaced? I've run 94,000 km now.
