TPMS Question

[Fyermanbob]

I've got 6 tires with tpms, 2 spares in the bed and have no warning lights on.

Do you have to relearn whichever four are on the ground if you change a tire? Or can the computer have more than four sensors learned at once?

Never had a problem with them setting of the alarm. The only time the alarm goes off is when one tire is low, even if it's one of the spares in the bed. So I guess the truck can "know" more than 4 at a time.
