Hi, all I currently have a 2011 FX35 RWD with the OEM 20" five spoke wheels and am looking to purchase a set of OEM 21" six spoke wheels. Want to find out if I can I pull the TPMS off my old 20" inch wheels to use on my new 21" inch wheels ?

I don't know definitively that it will work. But I've replaced a TMPS sensor on my stock 20'' wheel and do not see any reason why my sensor would not fit on a 21'' wheel. Do the new wheels have 'standard' valve stem hole placement? Perhaps you can run a parts query for a FX 20'' wheel TPMS and then for a FX 21'' wheel...if the same part number comes up, it is probably GTG.
