So i'm looking to buy 19" 16 spoke amg wheels for my 2012 coupe once it gets here. Im going to buy the rims from alloywheelsdirect and get the tires through my work.I'm wondering if I buy sensors from mercedes or an aftermarket company, do they have to be programmed at mercedes?I know some sensors can just be installed and after driving a few miles, they are good to go.Any input is appreciated.
