Iím currently running an Achilles Economist on my rear MC wheel but those tires are periodically hard to find. Iím thinking of switching to a 15x4 car rim with a -19 offset but donít want to give up my TPMS. Can the sensor for a cast rim be installed on a cast car wheel? If not, are there aftermarket sensors that are compatible with the system on my 2012 GSA?
