I have a 2010 accord LX with the 2.4 and I want to go from 16" to 19" rims and I heard the TPMS will not work on aftermarket rims and the light will stay on the dash?

 

You have to get TPMS sensors for your new wheels. Some types of wheels will not fit sensors, but many will. Take the sensors off your old wheels? Sell them with your old wheels so you don't have to dismount the tires? You can do that a few different ways.

You might need the dealer to plug in a scanner & set up for the new sensors.
