fronts stay more stable in pressure than rear because rear has more torquing force applied to them since 66% of the power is going to rear wheels vs 33% in front (100% to rear in rwd models)= rear tires have a more variable load...tire will compress under bigger load, making the volume inside the tire smaller, thus pressure higher and opposite under smaller load decompresses making bigger volume inside tire and thus lower pressure

Gaspam--- bad luck man!
So the tire is stable at 42 cold and 45-46 warm and staying stable without any further addition of air
Hopefully it'll stay

Mercedes-Benz AMG E63 & ML350 Bluetec
The only thing that used to slowly leak on my AMG's were small cracks in the wheels. These would not be visible from the outside, they all seemed to live along the inside of the wheel and were caused by potholes hits 9 times out of 10. Have not had an issue the the W212, but just an FYI. I had to have all four of my W211 wheels welded and repaired numerous times, but then again, those were made out of a brittle alloy. Good luck.

Will there be an open book (this post) quiz on all this?
