M3 non-runflat & TPMS

kevE90 · 10-02-2007, 04:43 AM

Just curious. We all know the M3 will not have run-flats. BMW throws in M-Mobility kit in the trunks. Now that in-tire TPMS are being used, what effect will that have. I'm sure the answer is none but I haven't a clue if the two play nice together.

Maybe the 2007 328/335 owners (w/TPMS) who have used the Mobility Kit (or conticomfortkit) know the answer?

I think there is risk of damaging valve/sensor which most people will find a minor thing. But do the M-Mobility/Conticomfort kits even work with these types of valves?

I thought BMW monitors tire pressure by monitoring changes in rotation speed...not the actual pressure?

I am referring to in-tire TPMS.

Yea, I know....did BMW switch?

They did switch on E90's, as of 03/07 SOP, now all 3er sedans and coupes have TPMS which uses an in-tire sensor to monitor actual pressure. If you use a product like "slime" or the goop that is part of the mobility kit, you will likely have to replace the sensor, which runs anywhere between $35 and $50. The hole in the sensor will get plugged up. Not sure if it can be cleaned up afterwards, but its doubtful.
