Tried the high pressure rubber stems with TST 507 Flow Thru and one started leaking so Ms. Amy and FT Turbs graciously sent me metal stems which I then had to trade for smaller steel ones that fit my wheels. Had the tires broken down and the steel stems installed and re-balanced with the sensors on them. Now, when we go to FL, I will re-torque the lugs a couple or 3 times the first day when we make potty stops, etc. I would suggest you balance the tires WITH the sensors as they will throw the balance off.
