You just have to reset it. Start your vehicle. Press the low tire pressure button down until the light goes out. then let go andpress and hold it down till it goes back on again. then start driving when the light shuts off again by itself it will be reset. It went off because the new tires are not the same hieght as your new tires. But it doesnt affect ABS or DSC.
