Quick update on my original post that started this thread... :) I decided to go with the Michelin Defender LTX MS/2 tires in the smaller 275/60/R20 size for my LE 2023 R1S (20" Brights). Now, I understand that 23,600 miles on the stock 20" Pirelli ATs is going to make those Pirellis sound...

Thanks everyone for all of the great data and perspectives on this! Really appreciate it. :) Based on the feedback, I have narrowed it down to the following options in the 275/60/R20 size (the consensus seems to be that sticking with the original size of 275/65/R20 is not the best for...

Thanks for the info! My setup is very similar: Gen1 Quad, El Cap exterior and OC interior, 20" stock Pirelli ATs, etc. but it's an R1S. And I get ~2.00 mi/kWh. We also got to Tahoe (but North shore so we go I-80) and L.A. as well. We are in Sunnyvale. So quite a similar use case to you just an...

I have looked at that as well but just can't find the data on the "20s" so I am a bit wary of extrapolating from comparisons regarding non-20s. Thanks!

Is the reason the Wrangler would have the worst efficiency of the group is that the Wrangler is not a "pure" AS tire and has some AT characteristics? Thanks for the info (especially on the compact spare)!

Thanks for the response. Appreciate it. :) Speaking about the Michelins, this is a good thread on Reddit that still is informative but does contain comments about no boost in efficiency. I took that to mean no efficiency boost when going from stock Pirelli 21s to Michelin 21s. There is the...

I know these questions have been asked before and there are some great compilation threads like this: ksurfier: https://www.rivianforums.com/forum/threads/affordable-high-efficiency-20-wheels-and-33-tires-options-275-60r20.24561/ but I am having a hard time distilling the wealth of info down...

So, at least for me, when I have this "cost of ICE vs EV" conversation with friends, I put it in terms of: "how much money do you have to spend to propel a given vehicle 100 miles?" I assume ~20 mpg for the ICE vehicle since I am comparing a 7 seat SUV ICE vehicle to my quad motor R1S Launch...

I have exactly the same question. My wife and I have a family plan and her music tastes and play history is certainly different than mine. When we play music via our Apple TV through our family room audio system, she can simply go to the Apple TV and change from my profile to her profile. But...

Jeez. Should have known that considering I used to be at Rivian in Palo Alto. Need more coffee obviously. LOL. Our R1S is a Bosch Quad Motor configuration. The Enduro motors are slick, though. Full specs: Version: R1S Launch Edition Exterior Color: El Cap Granite Interior Color: Ocean Coast...

Thanks so much R.I.P. for the quick response. :) So sorry for my ignorance but what does DM and QM refer to?

This is very helpful R.I.P. Thank you! Apologies up front. This is a long post. :) I want to submit a follow-up question just for clarification regarding "preconditioning best practice" under different scenarios given the summary from R.I.P. above. This is specifically focused on cold weather...
