I had the inflation light pop on last night, it's starting to get a little cool around here, so figured it was from the temp drop. idrive showed the front tire was down to 26 psi ,no biggie, stop by the local gas station and top it off.. I could not figure out how to get the caps off the valve stems.

Now this is my first BMW(2019, with 12k miles),I've only had it for a few weeks. The caps looked what I assume was factory. (Chrome with BMW logos on the end )I thought, maybe I need some special tool or there was some secret way to remove the caps...

Turns out all I needed was a hacksaw ,as all four caps were seized on..

So now my wheels are sporting a set of plastic caps, fresh off my lawn mower...

They were probably "seized" from thermal contraction due to the cold...I would've tried applying some heat before resorting to a hack saw...

They were defiantly seized due to galvanic corrosion, telltale chalky reside on threads that were under the caps... also it was 50 degrees Fahrenheit, if they were contracted that much at 50... they deserved to be cut off.
