When upgrading your wheels from factory, you have three options.

1. You can break down your factory wheels and pull the Tire Pressure Sensor Monitors from them, which is a hassle and means that you cannot easily sell or go back to your factory wheels in an emergency.

2. You can add new wheels without the sensors and just drive around with that annoying light on the gauges telling you that there is a problem.

3. You can have new Tire Pressure Sensor Monitors added when you buy your wheels from Latemodel Restoration Supply (LRS). You can also buy them seperately. These sensors are genuine Mopar parts and are specific to the Challenger. (We know, because we tried ones from a Charger and they did not work!)

Once installed and driven, these sensors will learn or pick-up the signal from the computer in the Challenger and that annoying light will go away within a couple of miles.

Don't be fooled, we found out the hard way.
