2019 M5C without MDrivers pack. Door plate states for 285/35/ZR20 a psi of 33.
Yet when the iDrive is set to the correct rear tyre size, I get messages staying that pressure is low and to drive below 80mph as low pressure from Tom's.
Tpms is showing as requiring 41 psi. So I have to set the tyres in use as 'other'
