TPMS-TST 5-6 degree difference on tires

[50-States]

I finally got to take my new 2021 Geo Pro 20 bhs out on a shakedown trip. Coming home I noticed a 5-6 degree difference between the tires. It was after dark on the way home so I know it wasn't caused by one side being in the sun. I pulled over for 10 mins and the temp leveled out. Is that normal or do I need to worry if a brake is hanging up, bad tire or bearing?

Also does the spare tire have sensor in it?

Thanks

SInce you did not indicate what the temps were... they may be within reasonable error... also
before there were electronic gadgets just a finger touching surfaces would tell you if things were getting too hot... like the hub, the tire and the metal wheel... they all might be warm to the touch but none should burn your finger and all should be very close in temp...

Agree with rsdata above. Put a hand on the hub(s) and check. The tires could be loaded differently depending on how the TT is stocked. Also a pretty good crown on the road could have the TT leaning a bit to one side. 5 or 6 degrees difference wouldn't have me to concerned.
