TPMS--------flow thru or not

Here's what I suggest. If your tires and valve stems are easily accessible without removing the hubcap, then use the non-flowthrough design and remove the anti-theft feature of the TPMS. Then it's a simple matter of unscrewing the TPMS by hand just as you would the stem cap. However, if your valve stem is pushing against the hub cap and you'd need to remove the hubcap to service the tire pressure, then I'd get the flow-through type and hope it solves the problem (although it could make it worse). In my opinion, the non-flowthrough is less likely to leak.

Neither should affect tire balance noticeably.
