| My personal opinion....i switched out the 19s for the amg 21s....added no sensors to the 21s and saved money....and had the dealer shut off the TPMS system so I dont have to worry if i change out the wheels at anytime...basically lift the car in the garage, swap the wheels, and go...no problems...of course unless you want to see the tire pressures and want the system on...however i can tell myself if something is abnormal in the wheels....i dont need a system to do that for me....good luck |
