As some of you know, I purchased a set of 20 inch chrome clad wheels off of a 2008 Dodge Charger RT. I had no problems for about one day and then the TMPS light came on and is on right now. I went back to the dealer yesterday and after carefull checking by the service manager the part numbers for the 2009 Dodge Challenger TPMS sensors and the 2008 Dodge Charger RT sensor are different. The fix will be to break down my 18 inch OEM tires and remove the TPMS sensors and put them on the 20 inch wheels. So for those few of you who are planning to buy a set of 20 inch chrome clad wheels from Ebay beware. You will still need your original TMS sensors or you will need to buy a new set from the dealer with the Challenger's part number. The sensors for the Charger and the Challenger are not the same.
