How can they not have tpms?No tpms
You can probably just mash down the sidewall and slip in the tpms right?So you paid to have the tires taken off and then paid again to have them remounted and balanced? You likely paid more than just buying some new tpms for the new wheels.

And whoever buys your wheels will have to both buy new tpms and pay to have the tires removed and then remounted and balanced...
