I'm buying a set of stock 18" wheels from a 2011 Mustang GT for my 2012 V6. They have the original stock TPMS sensors in them. One question is, how many years do they last? Also, do I need to get a reset tool (I see them on Ebay) to make them work on my car? These rims will need new tires, so maybe I should just buy a new set of sensors and a reset tool when I get the new tires. I wouldn't want the batteries to run out after I get new tires, and have to take the tires off. I was thinking of trading the sensors with my original ones, but if they only last several years, that seems like a pain. Just wondering what to do...
