Sensors are in the wheels with no physical wiring connections to the car.

If I needed to test for whether the sensor was working, what sort of tool would I need?
Do you park near the original wheels/sensors? What's the longest drive you've made since installing the new wheels? You have to drive ~40km's before the light will come on. I don't have sensors in my winter wheels, but the car reads the sensors from the summer tires in the basement as long as I park in the garage. On drives under the ~40km mark I don't get a light at all, even though the sensors are no where near the car.

As for programming, that can be done without removing the tires... no need to wait for the tires to be off.
