TPM error. Asking for 48 psi front and 50 rear

wasya152 · 03-31-2024, 11:20 PM

So we put the summer wheels back on and when resetting the tpm, we keep getting an error, tire pressure low, and it's recommending 48 psi front and 50 rear which I know can't be right. Anyone else get this and know how to clear it?

First thing I’d try is a soft reboot (hold down vol. knob for 20 seconds with car running).

If the tire settings are set at greater than 100 mph , the vehicle will try to force the pressures up into the 40s .Check the settings and set it to less than 100 mph. Then you have to drive to synchronize the sensors to the new setting. I run my summers at 30 psi cold and let them come up to 32 after warming up.

This, right here. Put the speed back down to less than 100MPH, this changed it back for me, as well. Not sure where they get the calculation for this, but its doesn't seem to work well for daily driving.

I believe the greater than 100 mph setting is for autobahn style driving, sustained speeds over 100mph. Its not really useful anywhere in the states. The blips we drive over 100 mph for a few moments does not count. I regularly drive my car over 100 at the track but still use the less than 100 setting.

I suggest you do a tire pressure measurement thru the iDrive menu (driving).
Mine's been throwing me low tire pressure warnings as of late even with pressures around 30-33 psi and the remeasuring procedure fixed it.
I have mine set to >100mph btw.

This is why. Set it to <100mph.
