So my black on black 300s is in need of new tires. I'm not a fan of the stock 19s, and I'm aware of the offset difference (the AWDs are +38 all around, correct?).

What I haven't found much information on, is what needs to be done regarding the TPMS? I want my TPMS fully functional after the upgrade. I'm looking at the Laser Mill GWG Flows, 20x9, with 255/45/20 rubber all around (Likely BFGoodrich Comp2-A/S)

Thoughts? Comments?

Normally, they get replaced as they are a wear item, they get old and brittle, and eventually fail.

What year is your car?

 

[uberDoward]

2012. I'm figuring they are ~4-5 years old, and the average life is ~5-7 years, so hey, may as well replace them while I'm putting on new wheels/tires.

Question is, which ones will I need? I see a bunch of different ones, and I want to make sure the ones I get will work with the OEM system.

For a 2012 you want the 433 MHZ units. The last set I got from Dorman for my SRT work very well. No problems.

Mine didn't need to be programmed but the 433 MHZ units may so make sure you read the descriptions. The factory part number is 56029400AE.

So the 56029398AB won't work?

 

[MADDOG]

Those are the right frequency as well. I can't tell from the descriptions I found if they need to be programmed or not.

Well, I've got 4 on the way, so I guess we'll find out!
