My car is on front 285/30/21 back 295/30/21 Michelin PS4S tires in the summer i use the other tire size/race tire settings and it works good I think it’s the most suitable setting.
I wonder what the tire settings do actually?
I noticed that the tire pressure calibration seems to take longer when choosing other tire size/race tire setting.

What settings do you use?
