The Rivian Tire Service Guide does not recommend the use of “jack puck” but to remove the rail plastic panel and place the jack under the lift point on the frame rail.

You can daisy chain 2 up to 4 Tesla Universal Wall Connector and share power…
Also, with future proofing (more like future hoping at this point ?), the Tesla Universal Wall Connector is capable of bi-directional charging. I hope that Tesla and Rivian will enable the feature in the EVSE and the R1.
I bought and mounted the same sensors without any issue - the R1S relearned them after driving for few minutes. Yours should have learned the sensors if they are functioning or programmed correctly.
I would have gone back to the tire shop and have them scan (they can even reprogram) the sensors...
Just got off the phone with the Gear Shop, and I asked in the end about the original price and the lady rep said they will honor the price of the Compact Spare when I first ordered my R1S (Dec 2021).
I did get hub centric rings (plastic) coz I am OCD like that. Americas Tire said I did not need them because the lugs that came with centers the wheel too.
EV1 website has this note under your wheel/tire set-up:
Recommended Factory Tire Size: 275/65/20. Select 275/60/20 if your Rivian came equipped with 22" wheels.
I run aftermarket set as well, 275/65/20 LT Scorpion AT plus (34.1 diameter) on 20X9 +18 wheels - way different set up from yours...
Here they are on 275/65R20 LT Pirelli AT plus.
Clearances are pretty tight on Lowest suspension height but no rubbing so far.
If I can change something it would be to ask the tire shop (if possible) to place the balancing weights more inboard vs right on top of the front brake calipers.
