TPMS sensors revisited - 1999 C5 / Aftermarket rims and tires
 

The PO of our car put aftermarket rims and tires on the car. He used normal valve stems. As a result we are getting the error message because there are no TPMS sensors.

I am exploring fixing this and was wondering if anyone could advise on TPMS sensors that will work on aftermarket rims without upgrading to the newer system.

I have contacted a reputable shop in my city but would like to be a little educated on this before I take it in.

I went with 4 new ones from OEWHEELSLLC. I di have to have them programmed though. Can't set with a magnet.
