all of this for my '11 WRX..............
just bought a set of OEM '12 WRX wheels with TPMS and OEM Dunlop summers (w/8k mi) for $600! SWEET! The wheels are worth $500, TPMS is worth $100, tires are worth maybe $300-400. I'm immediately turning it all around (as this would be my third set) and a new set of Dunlop ZII are going on this mint set with TPMS. Then selling off the my other set (no TPMS) and those OEM Dunlops... which are sold in advance. Then I'll sell off my 50% worn set of Dunlop ZI tires as stand alones. Likely worth $200-300
Overall, I exchange my very lightly (2 of 4) scuffed wheels w/o TPMS and get a mint set w/TPMS and new ZII tires for an overall cost of around $500
