I did not use the sensors on my 17" wheels, and only rarely have a light on my dash. I have had my car for over a month, and I bet the light has only been on for 5 days out of 34. Since I swap wheels/tires for seasons, it made no sense to install an extra set of sensors for the summer. If I lived someplace where it did not snow, I would just install the sensors from the factory wheels and call it done. Not so easy for us who live with 100+ inches of snow a year.
