Hi all,

Hope you are well.

My car is a 2020 M340i x-drive.

Recently, I noticed a very strange finding. I have done nearly 10 long trips, involving long-time motorway drives at 70MPH. So after I have driven long enough on the motorway, the rear right wheel's temperature will rise much higher than the other wheels while the pressure is in line with the other 3 wheels. So far the strange finding happens every time. The same effect also affects the right rear wheel temperature in urban drive but at a lower extent. Below is the illustration:

Before start:
Front wheel: Pressure 2.7; temperature 27

Rear wheel: Pressure 2.7; temperature 27

After motorway drive:
Front-wheel: Pressure 2.8/2.9; temperature 30

Left rear wheel: Pressure 2.8/2.9; temperature 30

Right rear wheel: Pressure 2.8/2.9; temperature 35

I have done wheel alignment and no strange findings. Any idea what is causing it? Other than the temperature difference, the car drives very well.

Many thanks in advance.
