Tile's in and will be grouting on Saturday (need a break from this project 'til then).
UPDATE: Tile & grout are done; toilet & vanity are in....mission complete as of 11/08/22!
Have replaced just by breaking the bead on the valve stem side, push down and R&R the TPMS/stem then reinflate. Balance is unchanged. Set of Delco TPMS (4) is about $60 on Amazon. Late ones have small battery.
