Re: Replace TPMS when replacing tires?
My decision in this same circumstance was to leave the old TPMS sensors in place. I didn't know how old they were as I had bought the car used, but the shop said the sensors were emitting a strong enough signal. I took a photo of one of them so I know what ones to order when the time comes. That will allow sensors of the exact same weight to be installed without a need for rebalancing, which will cut the installation costs if they fail before the next tire change.
