MERCEDES 4 wheel “Kit” is $322. - 4 TPMS sensors with stems
As the manual states - the size you are looking for is:
7 J x 17 H2 ET 48.5
Bolt pattern is: 5 X 112
Again, a millimeter higher or lower in offset will not make a noticeable difference.
Also, a 7.5 wide wheel with an offset of 44 will work as well.
The TPMS system is easy to reset from the dash display and then it will "learn" your new, Mercedes compatible sensors (or your old sensors in new locations) quickly after you drive a few miles.
