Do you mean TPMS (Tire Presure Monitoring System)? I am not sure what TPSMs are. Your Armada already has TPMS installed.

I'm putting 22's (devino lethals)

Best bet is to pick a set up from the dealer.

what do they usually run for a set?? im curious from the dealer i mean

Dealer wants between 60 to 75 per sensor. I sold mine to a forum member for way less than that. Just curious, why do you need new sensors? Why don't you use the four you already have in your stock wheels?

my dealership was selling em for $85 a piece. I put on 22's and the shop used the factory sensors but shattered one when putting the wheels on. Good thing there was a nissan dealership a few blocks away. Shop Manager was pissed when he got the quote over the phone. All I could do was smile.
