It's finally time to equip my stock 2019 JL Sahara with a lift kit, etc!

I am ditching the 31" tires and 18" wheels for 35x12.5 tires on 17x9 wheels.

I want to preserve the TPMS functions on the new wheels so I either have to move the old TPMS sensors from my old/stock wheels or get new TPMS sensors. Also, I notice that my TPMS system only reports each of the four mounted tires and not the spare tire.

So here are my questions:
1. Recommendations on move stock TPMS sensors to the new wheels?
2. Where can I get budget friendly new TPMS sensors?
3. What frequency does the Jeep JL TPMS sensor system use? 315MHz or 433MHz?
4. What about a TPMS sensor on the spare tire? Should the TPMS sensor report for the spare tire in my normal JL Sahara display? Does a lack of data indicate a lack of TPMS sensor in my spare now or does the system only display pressure for four tires?
5. When it comes to learning, I understand that the JL TPMS system will auto-learn which tire has which pressure without having to program unique sensor ids into it. Is that correct? Where can I read more about this process?

Thanks in advance!

I can answer a few of these questions:
1) I left the TPMS sensors in my tires that I took off and added new ones to the new set. (ordered through DiscountTire.com via DM of @discounttire on this forum) This allows me to sell the whole setup: rims, tires and tpms included.
2) I paid the Discount Tire upgraded $60 variety, I think they have some for $45.
3)I don't know and have not looked it up.
4)The spare tire should have a tpms sensor in it but it will not be picked up by the system. When I rotated my tires, the spare was automatically picked up and the system knows which tier is in which position.
5) With my new wheels, the TPMS picked up my new sensors within 15 minutes and was reading the pressures without me having to do anything at all. I was told that it could take up to 2 days for the new sensors to be read but it was only about 15 minutes in this case.

Hope this helps.
