emergency tpms question for 4/8/17

[Not_so_Breit]

Hey guys I have a super noob question for saturday.
So i just got 17x9 wheels with 245/45/17 tires for my brz. I am going to get the wheels and tires mounted and balanced tomorrow but bought form and function colored lugs and the place I am going doesn't have a soft wall socket to put them on so I am going to just drive them down the road to my house to put them on.
Ok so here is where I get dumb, so if the tire place takes the tpms off my rims and puts them on the new rims while they aren't on my car but they are in my car and I drive home will the light be gone once I swap the rims out?
Also will the different rims size throw a light? Will I have to go to subaru to have the tpms like reset or anything?
I know nothing about tpms since Ive never had a car with it so any info anyone can give would be super helpful so I know what I'm getting into tomorrow

No worries on different rim sizes... TPMS only cares that it sees 4 sensors and that all 4 are within 5 PSI.

Light does not come on right away, and sensors only transmit when rotating so your light may never come on. Since you are reusing same sensors I am fairly sure light will clear itself if it does come on

245/45 is a full inch too tall. You speedo will be off by about 4%. I guess it is too late now. Otherwise you are fine.
