I still have original Contis on my car, but they are gonna get replaced with JMHK's Conti DWS's in a few weeks.

The guy at the tire shop didn't even want to try to talk me into new TPMS thingies... but he said they would replace them and "set them up" to work with the car.

Just not sure I want to blow the money. SO........... if they replace them, what is involved in "Teaching" the car to talk to the new ones?

What are the chances this will cost me another hour of my day? Should I just leave the original senors on the rims? If I replace them is that the same as the old "New valves and stems" or not? I always ask for new valves and stems cause there is no need to re-use a cheap part that can fail.

ANyone want to explain if the TPMS things ARE the valves/stems?
