Thanks for the response @B Digs.

Got them mounted today! (Also scheduled an appointment with the SC for December to get them calibrated)

Switched from 21s. Had the

Rivian updated the software yesterday from 21s to 20s. Efficiency to date:

I don’t get it, 21” to 20”? Rivian offers two 20” size tires

AT 275/65/20 34.1” diameter
AS 275/60/20 33” diameter

Did they program it to All Terain or All Season?

it is what Rivian recommended and (related) it would provide more accurate range estimates. I of course could be mistaken.
My assumption is that the setting would be essentially the same as the Gen 2 T with the same tires.
I'll see what Rivian says and if I hear back will post it.
Can you go into the truck info page and send a pic of what wheels it says you have?

Yeah if they did the change to the Gen 2 size 275/60/20 AS Goodyear tire then that’s great to hear. But if they did it to the 275/65/20 AT size then they did you wrong. Let us know thanks.
Spoke with a couple of people in service and they confirmed that the Gen 2 size 275/60/20 AS Goodyear tire is the ideal setting but isn't available at this time for Gen 1 vehicles (think B Digs has gotten the same response) and that the 'closest' setting for now would be 275/65/20 AT (and that is what my software is set to). They indicated that the change wasn't necessary and either setting would be fine (and not hurt the vehicle) but they currently set it to the 275/65/20 AT until they can update the Gen 1 software settings (not sure when that will happen).

If you were coming from the 21" wheels, they should have left the software unchanged as the diameters are nearly identical...

Here is the difference now that they have updated the software.

Hopefully Rivian will eventually allow the software to be updated to the new size.

I assume Rivian would prefer the guessometer to be closer to reality than speedometer or odometer, to prevent people from complaining about their vehicles getting "less miles" than estimated by the vehicle.

I've been running the settings as 21s with 275/60R20 AS and AT tires for the last year / 20k miles, while the guessometer is usually wrong, the navigation arrival miles is pessimistic and usually improves over the course of a drive. I much prefer this to driving 4mph under the displayed speed and having 3% more miles on my odometer.

Wait till 1k miles for tires to break in before posting efficiency.

I saw these again this week picking my truck up, they're sitting in my DT cart staring back at me with those sad kitten eyes. Damn it @B Digs why did you make the perfect tire? What's am I to do with my old tires?
Posting results after waiting ~1500 miles. I drove 360 miles on Sunday and averaged 2.24. On the same drive ~3 months earlier (albeit in warmer conditions) on 21s, my average as 2.44. I think that's pretty decent. Honestly, I didn't expect much better than this.

Quick update on my 20" Goodyear - could not be happier :) Went from 21"

So after almost 8k, I am down to 10/32. All 4 tires wearing the same, so not sure if I will do a rotation. Average consumption - 2.3 miles per kWh, so 5% less than what I was getting from 21". As a reminder, 21" after 17k miles were down to 6/32.

Nice! Glad to hear you like your "new" tires!

Tough call on the rotation, but might be helpful for longevity even if all 4 appear to be wearing the same.

Yep, will still do a rotation but just a bit late than usual. This is really connected to alignment - I have near perfect alignment (after few tries SC nailed it), this is why the wearing is even and very minimal.

I went to order these from Discount Tire, but all they seem to have is the Wrangler Territory HT (not AT) in the 275/60/20 size. Does anyone else have this issue?

They suggested that I order from Tirerack.com which delivers to Discount Tire for installation, they are the same company.
(They take much longer to test the tires for compatibility before putting into their system)
