I recently bought a set of steel rims for the winter that have TPMS sensors installed. I was told that my 2015 Silverado can "remember" up to 8 TPMS sensors so if I had the winters rims calibrated to my truck, I would not have to relearn the sensors twice a year when I swap out my winter/summer wheels. If this is true, it would be worth it for me to pay the dealer one time to calibrate my winter sensors to my truck. But if this is not the case, I would be better off buying a tool and doing it myself rather than pay for it twice a year. I am trying to figure out what is more economical. Can anyone help me out? Thanks in advance
