hey guys, i just want to put out, not sure if you guys already know, but i do recall a few people having a leaky tmps with new rims. a easy fix for that instead of getting a new tmps or grommet is putting some silicone sealer around the threading of the tmps...works like a charm

 

one of mine leaks too, but it leaks from the valve stem core, not the TPMS body. tries tightening it down, but it still slowly leaks.

 

maybe try replacing the valve stem core?
