My wheels are in, went with the 20's. Now...I know there are two diffrent tire pressure sensors used on the Charger. I think one is for the SRT wearing 20" and the other is the rest of the sizes. I'm going to keep my factory shoes for winter driving and I'm thinking about getting another set ofOEM sensors for the 20's. Do you think it's worth it to have the dealer do a seaonal recal on the computerevery year for the diffrent sizes? Will the 18" sensors read correct in the 20" shoes? I can't stand the thought of driving around with that dopey light on in a new car. Please any one that has a clue or has changed sizes chime in!

You might consider getting another set of valves (they come with sensors) for the new set of wheels. I've seen prices between 37-41 per sensor. Other than that a programer would be very handy to have so you could change the tire size yourself.

Gotcha.. kinda. I'm gonna order the TPS for the 18" tires from one of the forum sponsors. $30.95 as opposed to $41 from my dealership and see how that goes.
