I am not sure how to confirm I will take a look to see if I can find a way. I did not buy new TPMS when I bought new wheels. I can still see tire pressure inside the cabin of the car which makes me assume there still are TPMS with the new wheels. That said on the Martian Wheels website they say TPMS are needed for pre 2021 model year cars which mine is a 2021. Let me see what I can find and I will get back to you.
